Methacrylate adhesives show their strength

The integrity of structural adhesives
Structural adhesives are fast emerging as the preferred alternative to conventional mechanical techniques, such as bolts, rivets and welding, for bonding a wide variety of materials. 

Comprising three main categories, including epoxy, polyurethane and methacrylate, the benefits of structural adhesives are now well documented. Providing a low weight answer to today’s engineering issues, they can be used to bond a variety of substrates, facilitating the strength and integrity of bonded structures whilst lowering stresses, enhancing chemical and temperature resistance, and optimising manufacturing methods.
 
Design trends
There’s no doubt that a variety of composite, plastic and non-plastic materials will continue to play key roles in the drive to create lighter structures across different industries moving forward – from the electronics industry, through to the automotive, aerospace, general transport and oil and gas industries, the list goes on. The consequence of this trend is that various material combinations will need to be bonded together, and structural adhesives are set to play an even greater role in facilitating this.
 
Performance
When you look at how the trend in using various material combinations is evolving, you begin to see why demand for methacrylate adhesives is rapidly increasing. 
Based on thermoset adhesive formulations that provide excellent structural properties, the combination of polymers and impact modifiers have seen methacrylate adhesives emerge more recently to fully compete with polyurethane and epoxy adhesives.
 
Methacrylate adhesives provide a special balance of high tensile, shear and peel strengths with the maximum resistance to shock, stress and impact across a wide temperature range. They can generally be applied without any or little surface preparation when joining similar and dissimilar materials. 
They are extremely versatile in offering good gap filling (up to 8mm) and speed of cure characteristics.  In addition, methacrylates are tolerant to off-ratio mixing, and remain strong and durable under severe environmental conditions.
 
Araldite 2048 and Araldite F348
These methacrylate adhesives exhibit some of the highest lap shear strengths available (24 MPa on aluminium), along with high elongation, making them ideal for dynamic loading. These benefits are offered in combination with good chemical resistance, low ionic content (for electronic applications) and ease of application. They also maintain extremely high impact resistance and elasticity at subfreezing temperatures.  
 
These properties are particularly advantageous for industries such as the oil and gas sector, where these adhesives have been used to assemble offshore polycarbonate pipes onto steel housing, or in the electronics sector, where they have helped both stainless steel and coated substrates withstand impact resistance and vibration. 

They demonstrate that it is possible to achieve bonding between different materials whilst managing structural and weight issues within the design concept.  By being generally faster setting than other adhesives and requiring little or no surface preparation, methacrylates facilitate an even better manufacturing solution.

The GoodLife® bio sip-lid is firm and comfortable to drink from and can be used safely even with the hottest drinks. Because of the flexible sturdiness of bagasse, the bio sip-lid fits tightly on all 90mm diameter 12oz and 16oz paper hot cups in the UK market. Indeed, tests have shown that the lid stays securely on the cup even if the cup is tipped over.

Speaking about the lid, commercial director Danny Feldman commented "what we love about this lid and what makes it truly stand out from all other sip-lids is that everyone will know it is eco-friendly as soon as they set their eyes on it. There are expensive PLA lids that are compostable available but unless you know what you are looking at it looks just like and can be easily mistaken for any other plastic sip-lid. The GoodLife® bio sip-lid looks, feels and is the most eco-friendly lid on the market today".

The introduction of the GoodLife® bio sip-lid follows several years of research and development and is protected with European Community Design Registration. The GoodLife® bio sip-lid features a visual of their brand icon Eco the Friendly Frog and the word compostable, making it instantly recognizable as an environmentally friendly product.
Price-wise, the bio sip-lid falls approximately midway between the usual market prices for high impact polystyrene and crystallized PLA lids and will therefore be welcomed by the trade as a realistic biodegradable alternative to plastic.
GoodLife® is a registered trademark.

SGL honors professor Klaus Müllen with the Felcht Award for services to graphene research

The Carbon Company – has honored Professor Klaus Müllen with the Utz-Hellmuth Felcht Award for his research into the synthesis of tailored graphenes. Professor Müllen, Director of the Max Planck Institute for Polymer Research, received the award on July 18 at the International Carbon Conference in Rio de Janeiro, Brazil.





Dr Gerd Wingefeld, a member of the SGL Group Board of Management, said: “We present the Utz-Hellmuth Felcht Award to honor outstanding scientific and technological contributions in the field of carbon and ceramic materials. The extremely strong, electrically conductive carbon material, graphene, has immense application potential in computer chip manufacture, as a composite material for energy storage in batteries and fuel cells, and as a catalyst. Professor Müllen and his team have made an important contribution here. The synthesis process developed by him makes it possible for the first time to produce graphene nanoribbons with precisely defined shape and size.” 

Graphene is a very good electrical conductor, ultralight, stronger than steel, chemically resistant, and virtually transparent. In 2010, Konstantin Novoselov and Andre Geim were awarded the Nobel Prize in Physics for their work on this two-dimensional carbon material. In 2013, the European Commission chose “Graphene” as one of its first largescale research projects to be funded with up to a billion euros over 10 years under the “Future and Emerging Technologies Flagships” (FET) initiative.

Polyonics Presents Flexible Woven Nylon Label Material for Wire & Cable Bundles & Lab Applications

Nylon label materials can offer significant advantages over polyester or polypropylene based films in terms of conformability. This is very important when labeling rounded surfaces such as vials or test tubes used in medical and laboratory applications or identifying wire and cable bundles for the electrical industry. The label needs to survive the life of the part identified and stiffness of a polyester or polypropylene material, over time, may cause failures such as flagging or delamination. The flexibility of the nylon label would all the material to conform to a rounded surface and be less likely to see this type of failure.


Why is nylon better? When compared to continuous film, the woven nylon absorbs the stresses that result from dimensional changes that occur from bending or at extreme temperatures. The aggressive 1 mil pressure sensitive adhesive allows for a strong bond in extreme low temperature when adhered to rounded plastic or glass surfaces.
The XF-302 is a 5 mil woven nylon cloth with a 1 mil aggressive adhesive that will not flag or otherwise detach from a rounded or curved surface. The flexible design has been tested in an outside laboratory for cryogenic storage applications where the temperature can be as low as −196°C.
These products are used in many applications across multiple industries including:
  • Slides and glass plate identification
  • Test tube and vial tracking
  • Wire marking
  • Bundle wraps
  • Cryogenic storage

Braskem to Supply Bio-based LDPE to Tetra Pak for Carton Packages Produced in Brazil

In a first for the carton packaging industry, Tetra Pak® announces that it plans to sign an agreement with Braskem, the largest thermoplastic resins producer in the Americas, for the supply of low-density polyethylene (LDPE) made from sugar cane to its packaging material factories in Brazil.
This breakthrough initiative, which will be limited in scope to Brazil only for the duration of the trial, is scheduled to start during the first quarter of 2014. According to the plan, Tetra Pak will use bio-based LDPE as a component of its packages produced in Brazil. The planned move to bio-based LDPE means that 100% of Tetra Pak packages produced in Brazil, about 13 billion, will have up to 82% packaging material from renewable sources.

"The new agreement to be signed with Braskem demonstrates our commitment to bring environmental innovations to our customers and is a further step in our journey to develop fully renewable packages," said Tetra Pak President and Chief Executive Officer Dennis Jönsson.
Braskem will use ethanol derived from sugar cane to produce ethylene, which will then be converted into LDPE. The LDPE made from renewable sugar cane has the same technical properties as LDPE made from fossil sources, and the environmental benefits of being from a renewable source. Braskem biopolymers are known under the trademark I'm green™.

"The new bio-based I'm green™ LDPE is as inert, resistant and recyclable as the polyethylene made from fossil sources but, contributes to the reduction of greenhouse gas emissions by absorbing carbon dioxide from the atmosphere during the sugar cane growth process," said Braskem President Carlos Fadigas. "The expansion of the green products line reinforces our commitment to adding value through sustainable development for the value chain."
Since 2008, Tetra Pak's paperboard supplies in Brazil are certified by the Forest Stewardship Council™ (FSC™), which means that all the paper used in the production of Tetra Pak packages in Brazil comes from forests managed in accordance with responsible forestry management principles and other controlled sources.

Tetra Pak was the first liquid food packaging supplier to use bio-based plastic in its packaging, launching Tetra Brik® Aseptic packages with StreamCap™ 1000 produced with bio-based high density polyethylene (HDPE) supplied by Braskem in 2011. Earlier the company announced global availability of a bio-based version of LightCap™ 30, which uses HDPE made from sugar cane.

Hexagon Composites receives a Titan order

Hexagon Composites' subsidiary, Hexagon Lincoln has received an order from a new North American client to supply Titan natural gas transport modules. The value of the order is approximately USD 9 million.

A North American gas supplier, will use the lightweight Titan modules for transportation of compressed natural gas from pipeline-connected mother stations to stranded industrial users traditionally powered by conventional liquid fuels.

Compared to conventional steel offerings, Titan modules are lighter and transport more payload per trip. With its significantly lighter weight and substantial transport capacity, the type 4 composite tank Titan modules can be used where road weight restrictions might otherwise hamper deliveries or where maximum capacity is critical to reduce miles traveled. Operations using Titan units have proven to reduce fuel consumption in operation by more than 40% compared with conventional steel trailer technology.

Delivery of the Titan modules will begin in the third quarter of 2013.

NASA tests game changing composite cryogenic fuel tank

Cryogenic propellants are gasses chilled to subfreezing temperatures and condensed to form highly combustible liquids, providing high-energy propulsion solutions critical to future, long-term human exploration missions beyond low-Earth orbit. Cryogenic propellants, such as liquid oxygen and liquid hydrogen, have been traditionally used to provide the enormous thrust needed for large rockets and NASA's space shuttle.

In the past, propellant tanks have been fabricated out of metals. The almost 8 foot (2.4 meter) diameter composite tank tested at Marshall Space Flight Center in Huntsville, Alabama, is considered game changing because composite tanks may significantly reduce the cost and weight for launch vehicles and other space missions.

Switching from metallic to composite construction holds the potential to dramatically increase the performance capabilities of future space systems through a dramatic reduction in weight. A potential initial target application for the composite technology is an upgrade to the upper stage of Space Launch System heavy-lift rocket.

Built by Boeing at their Tukwila, Washington facility, the tank arrived at NASA in late 2012. Engineers insulated and inspected the tank, then put it through a series of pressurized tests to measure its ability to contain liquid hydrogen at extremely cold temperatures. The tank was cooled down to -423 degrees Fahrenheit and underwent 20 pressure cycles as engineers changed the pressure up to 135 psi.

The NASA and Boeing team are in the process of manufacturing the 18 foot (5.5 meter)-diameter composite tank that also will be tested at Marshall next year.

"The tank manufacturing process represents a number of industry breakthroughs, including automated fiber placement of oven-cured materials, fiber placement of an all-composite tank wall design that is leak-tight and a tooling approach that eliminates heavy-joints," said Dan Rivera, the Boeing cryogenic tank program manager at Marshall.

Composite tank joints, especially bolted joints, have been a particularly troubling area prone to leaks in the past. Boeing and its partner, Janicki Industries of Sedro-Woolley, Washington, developed novel tooling to eliminate the need for heavy joints.
