NatureWorks to Commercialize Ingeo M700 Lactide Biopolymer for Industrial Applications by 2013

NatureWorks LLC has announced that as part of a major capital investment at its Blair, Nebraska, Ingeo™ lactide and biopolymer manufacturing facility, the company will be the world's first to offer in commercial quantities a high-purity, polymer-grade lactide rich in the stereoisomer meso-lactide. Identified as Ingeo M700 lactide, the new material can be used as an intermediate for copolymers, amorphous oligomers and polymers, grafted substrates, resin additives/modifiers, adhesives, coatings, elastomers, surfactants, thermosets, and solvents.

Until now, several niche-focused producers have attempted to address the functionality requested by the market with what are described chemically as racemic lactides. "Compared to these, the high-purity Ingeo M700 will be lower in cost, easier to process, and an overall better alternative to high-priced racemic lactide, as well as L and D-lactides, in a host of industrial applications," said Dr. Manuel Natal, Global Segment Leader for lactide derivatives at NatureWorks.

As compared to racemic lactide's melting point of nearly 130° C, and L and D lactide's 97° C, Ingeo M700's melting point is below 60° C. This makes for a more effective chemical intermediate on a number of different levels. For example, Ingeo M700 offers a more efficient way to deliver ester functionality and, because it is effectively an anhydrous form of lactic acid, processors will not have to deal with water when using Ingeo M700. Meso-lactide is up to two times more susceptible to ring-opening reactions than L, D, or racemic lactides, which can mean less catalyst usage, lower reaction temperatures, or both. It can be processed below 70° C, which under most circumstances eliminates the need to handle expensive solid particles and allows easier processing.

NatureWorks was the first company in the world to manufacture a biopolymer in commercial quantities. Today, Ingeo is one of the world's leading biopolymer brands and is used in rigid and flexible packaging, electronics, clothing, housewares, health and personal care, semi-durable products, and food service ware. In 2010, NatureWorks began offering high-performance L-lactide intermediates.

By early 2013, the company will offer thousands of tons of Ingeo M700 lactide. Prior to this availability, meso-lactide samples will be available in 2012 to advance market development.

Andromeda Selects Net Cages Made of Dyneema® Fiber for Maintaining Efficient Aquaculture

Fish farming plays a key role in providing a sustainable source of protein to the earth's ever-growing population. Increasing international demand for all types of sea food is driving the aquaculture industry to develop more economic and extensive operations. (Aquaculture encompasses not only fish farming but also farming for shrimps, oyster, seaweed and other species.) This places huge demands on equipment, manpower and materials as well as the environment.

Greek aquaculture company Andromeda aims to become the leader in its field in the Mediterranean. It is using nets and cages with Dyneema® ultra-high molecular weight polyethylene (UHMWPE) fiber to sustain healthy growth and above-average profitability. Greece is a key country in aquaculture in the Mediterranean and Andromeda is one of the country's top five aquaculture companies.

Andromeda started using netting made from Dyneema® more than five years ago (2005). Today it has over 80 nets with Dyneema® installed. This accounts for almost 25% of all nets Andromeda uses for sea bream farming. Andromeda is considering using nets with Dyneema® for sea bass as well.

"Net cages made with Dyneema® fiber are lighter and stronger than cages made in other, traditional fibers. They are also much easier to handle. As a result, they provide a safer working environment by reducing bodily strain and physical requirements. The lighter nets also require 40% less use of antifoulants than nylon nets", says Antonis Raftopoulos, Purchasing Manager at Andromeda. "This not only has a positive environmental impact but also produces significant cost savings."

Dyneema® fibers are highly impervious to wear and tear. They resist fish bites much better than other materials, so fewer fish escape, and their high resilience hampers predators like seals, turtles and bluefish from damaging and entering the cages. Dyneema® is also helping Andromeda cut maintenance costs. "We are confident that with Dyneema®, we can reduce diving inspections by 50%" says George Tzamalis, Production Supervisor at Andromeda. "Furthermore, nets made from Dyneema® only need cleaning every 12 months, while nylon nets have to be cleaned after 7 months. Netting with Dyneema® has a smaller diameter meaning up to 30% less surface area to catch dirt. When using a clean net from Dyneema® the fish grow faster and better."

Andromeda expects the benefits to last over time too. "We expect nets with Dyneema® to have a lifetime at least equaling that of nylon nets," comments Antonis Raftopoulos. "Our experience is that nylon nets show a steep decline in performance after some years. In contrast, nets with Dyneema® only lose strength gradually over time. They are worth the investment as they lead to overall savings of 10 to 15%."

"Dyneema® enables net manufacturers and fish farmers to harness a range of performance benefits that aid sustainable development," says Andre van Wageningen, Global Marketing Manager at DSM Dyneema. "Andromeda is the latest of many end users to have experienced the various benefits that nets with Dyneema® bring, and I am sure there will be many to come. DSM is committed to a sustainable future by driving innovation that generates value."

Applied Nanotech Gets Grant to Develop CNT Reinforced Improved Hydrogen Fuel Tanks for Vehicles

Applied Nanotech Holdings, Inc., has announced that it has been awarded a Phase I SBIR grant, in the amount of $149,426, from the US Department of Energy to develop ultra lightweight hydrogen fuel tanks using carbon nanotube reinforcement.

This grant was awarded for a 9-month program with an overall objective to significantly improve the mechanical properties of the carbon fiber/epoxy material used to construct the hydrogen fuel tanks using carbon nanotube reinforcement. The primary goal is to reduce the weight of the tanks by 20 to 30 percent. A weight reduction of this magnitude will not only significantly lower the hydrogen fuel tank costs but also increase the vehicle's fuel efficiency.

The International Association of Natural Gas Vehicles reported that sales of composite pressure vessels are expected to reach $250 million by 2013, and upwards of $560 million by the end of the decade; the adoption of nanotechnology enhanced resins in high pressure hydrogen storage vessels represents an immense opportunity for near term commercialization. Today, the price of carbon fiber is the main driver of the hydrogen pressure vessel's cost; by incorporating carbon nanotubes into the resin matrix, the resin itself can absorb much of the load currently absorbed by the carbon fiber reinforcement. Using carbon nanotube enhanced resins will undoubtedly decrease the carbon fiber required to construct a functioning hydrogen pressure vessel. The value of this decrease will not only be realized in lower material costs but also in lighter pressure vessels, enabling a more streamlined manufacturing and supply chain process and ultimately a more efficient vehicle.

Applied Nanotech has developed carbon nanotube reinforced epoxies, vinyl esters, and polyesters for carbon fiber and glass fiber reinforced composites. These composites can apply to a wide range of products including: sporting goods, aerospace, automotive, renewable energy, ballistics, and many other applications.

"I am very pleased to see that our nanocomposite technology, first commercialized for sporting goods badminton racquets and golf club shafts with Yonex Corporation, is starting to gain traction in other commercial applications with very large market potential," said Dr. Zvi Yaniv, CEO of Applied Nanotech, Inc.

"Nanocomposite materials are a very important part of our business. We are currently working with a variety of companies across several industries to tailor our composite materials to improve the underlying products of our potential customers," said Doug Baker, CEO of Applied Nanotech Holdings, Inc.

Japan Wool Utilizes SABIC's Flame-retardant PEI Fiber for Blending to Produce Protective Garments

SABIC Innovative Plastics has announced that its versatile, high-performance Ultem* polyetherimide (PEI) fiber has found an important new application in high-end work wear and protective clothing. Japan Wool Textile Company, a division of NIKKE Group, is now blending Ultem fiber with wool and other materials to produce yarn, fabrics and garments that offer a unique combination of comfort and protection, including permanent, non-halogenated flame retardance (FR) and excellent ultraviolet (UV) resistance. Unlike traditional aramid materials, Ultem fiber can be easily and cost-effectively colored in a wide range of shades using conventional polyester dyeing processes, enabling Japan Wool Textile Company to enhance the aesthetic appeal of its new line. SABIC Innovative Plastics continues to penetrate and grow new market segments and expand the range of applications for its globally proven Ultem resin technology to give customers innovative new options for product differentiation and exceptional performance.

"The work wear and protective clothing sector has outgrown traditional materials, and our Ultem fiber offers a significantly better option," said Kim Choate, Global Product Marketing Manager, SABIC Innovative Plastics. "This flexible, soft and colorable fiber provides superior comfort and aesthetics, plus sustainable FR technology and the highest level of protection and durability for workers in safety-focused industries such as oil and gas and chemicals. We foresee many other uses for this versatile fiber, which has already broken new ground in composite aerospace boards for aviation interiors, filtration media and other demanding applications."

"Following a rigorous development process, we launched a completely new flame-retardant material by using Ultem fiber," said Takanobu Matsumoto, General Manager, Japan Wool Textile Company. "Particularly in the areas of improved comfort and colorability, our new work wear products will provide major benefits for customers and address unmet market needs. This SABIC Innovative Plastics technology has also helped us to establish an overseas market for our work wear."

Japan Wool Textile currently offers shirts, trousers, jackets and coveralls in an Ultem fiber-rich blend, as well as yarn and woven fabrics.

Tough on Protection, Easy on the Worker:

Ultem fiber's unique combination of properties fills a longstanding need in the high-end work wear marketplace. Traditional work wear, particularly clothes made from meta-aramids, are stiff and uncomfortable. They also are difficult to dye, thus limiting the ability to produce custom-colored items that support a company's brand. In contrast, Ultem fiber is soft and flexible for improved wearability, and can be dyed in many different colors using existing infrastructure, helping to drive down system costs. It resists degradation from UV light, making the material a potential candidate for outdoor wear.

Ultem fiber is inherently and permanently flame retardant. It utilizes proprietary technology that avoids the addition of environmentally hazardous halogens and cannot wash out of the garment, as many FR agents in low-end fabrics can.

This material offers excellent heat resistance meeting the European Union (EU) EN 531/ISO 11612 and U.S. National Fire and Protection Association (NFPA) 2112 standards, and provides low smoke and toxicity performance.

NJIT Researchers Focus on Making Corn-based Epoxy for Promoting Green Plastics

NJIT Research Professor Mike Jaffe's recent book chapter about sugar-based chemicals is topping the American Chemical Society (ACS) book series' must-read list.

"Sugar-Based Chemicals for Environmentally Sustainable Applications" appeared in the most recent ACS Symposium Series and is racking up kudos. Co-authors were Xianhong Feng, a Doctoral Student and Research Professors A. J. East and W. Hammond, all at NJIT.

The popularity stems from the topic, an overview of isosorbide and its potential role creating polymers and small molecules. The chapter features new and better ways to replace the dreaded bisphenol A (BPA) in manufacturing processes. In 2009, Jaffe's team was awarded a patent for a chemical derived from sugar. The new material uses a corn byproduct, isosorbide, to create a derivative that can be used to replace bisphenol A (BPA) in epoxy resins. Such resins are used in a number of adhesives and coatings of consumer products, including those used in the lining of tin cans. The researchers recently received another patent to compliment the earlier one.

"The new patent will help create a less toxic epoxy resin," said Jaffe. Such resins are polymers widely used as adhesives, paints and coatings to protect food in cans. Jaffe has been developing sugar-based materials in conjunction with the Iowa Corn Promotion Board (ICPB) in an effort to promote and create new, commercially attractive, sustainable chemistries from wider uses of corn. This new sugar derivative can be obtained from corn. The two patents are part of a series filed by the ICPB and NJIT to develop applications and markets for sugar-based chemistry.

"Renewable materials made from corn are gaining ground for new industrial plastics markets," said Rod Williamson, Iowa Corn Director of Research and Business Development. "Making epoxy from corn can be a win-win for public health, plastic manufacturers and for farmers."

Sugar-based chemicals can be used as building blocks to produce new monomers, polymers and additives for the commercial plastics and cosmetics industry. These are materials generally recognized as safe sugar compounds with a unique stereochemistry providing a ubiquitous platform for making cost-effective chemicals and polymers.

The book chapter focuses on isosorbide and its isomers as sugar-derived dianhydrohexitols. The two can be either incorporated in the backbone of new polymers or converted to low molar mass additives for thermoplastics and thermosets or as specialty chemicals. As the cost of petroleum rises, the attractiveness of renewable feedstocks for producing value-added products increases. The emergence of sustainable sugar derived chemicals (especially isosorbide modified products) offers attractive prospects with high potential for the next generation chemical industry.

Much attention has recently focused on BPA, which has been known to have estrogenic properties since the 1930s. BPA is widely used in processes that result in the lining for tin cans and key ingredients in plastics ranging from baby bottles to nail polish. Unfortunately, the chemical bonds that link BPA in polymer structures are not completely stable and the polymer may slowly decay with time, releasing small amounts of it into materials with which it comes into contact, such as food or water. Recent studies have shown the widespread presence of tiny amounts of BPA in the environment. Even at minute levels BPA may still exert estrogen-like effects on living organisms.

The ACS Symposium Series contains high-quality, peer-reviewed books developed from the ACS technical divisions' symposia. Each chapter is carefully authored by an expert in the field, and the collection of chapters edited by an internationally recognized in the field. The series covers a broad range of topics including agricultural and food chemistry, cellulose and renewable materials, chemical education, organic chemistry, polymer chemistry, materials, and many others.

HDPE with Improved Melt Flow Rate Serves to Make Complex Injection-molded Medical Devices

Bormed HE9601-PH conforms to European and US Pharmacopeia and is registered with Drug Master File.

Boeing to boost 737 production rate to 42 airplanes per month in 2014

Boeing Commercial Airplanes President and CEO Jim Albaugh said the market outlook for single-aisle jetliners is strong and growing.

"Customers are demanding our Next-Generation 737 at an unprecedented rate," Albaugh said. "New performance improvements and enhanced passenger comfort features have driven home the value equation for our customers."

Albaugh emphasized the popularity of Boeing's new passenger comfort features, noting that since its introduction in May 2010, the new Boeing Sky Interior is specified on more than 80 percent of new 737 orders.

737 Program Vice President and General Manager Beverly Wyse said the goal with this rate increase is to continue meeting customer demand with an innovative airplane that provides strong performance and value.

"We have worked very closely with our supply chain and our world-class manufacturing team to ensure we can increase rate in an efficient and responsible fashion," Wyse said. "We believe that many of the capital investments and production system changes made for 38 airplanes per month will already position us to build 42," Wyse said. "We are very well situated for this rate increase."

The 737 program currently produces 31.5 airplanes per month and expects to go to 35 per month in early 2012, 38 per month in second quarter 2013, and then to 42 per month in the first half of 2014.

The rate increase announced today is not expected to have a material impact on 2011 financial results.

Boeing's highly efficient and reliable 737 family has become the best-selling airliner in history. More than 280 customers have placed more than 8,880 orders for the single-aisle airplane – including more than 5,750 orders of the Next-Generation 737. Boeing currently manages a backlog of more than 2,100 of the 737 family.
