Gas Diffusion Layer Made of Carbon Fiber Fabric for Fuel Cells

Owing to the increasing demand of fuel cells, Toho Tenax has developed an improved gas diffusion layer (GDL) using carbon fiber fabric that is meant to be used in fuel cells as an electrode component. The innovation is claimed to perform high-speed roll-to-roll processing. In the absence resins, unlike paper-based GDLs (carbon fiber sheets impregnated with resins), the improved GDLs show better water permeability, lower contact resistance (uniform textile surface obtained by spinning, weaving, and carbonizing), flexibility and strength. The new GDL will be available in 260µm and 320µm thicknesses; the development of 200µm ultra-thin fabrics is underway. This improvement in carbon fiber fabric can enhance performances of mobile devices, stationary power supplies and fuel cell vehicles.

Chennai evaluates to run its bus service on CNG

In order to reduce the emission levels and operational costs, the government-owned Metropolitan Transport Corporation (MTC) intends to powered is bus fleet by compressed natural. Consequently, the company recently held meetings with Indian Oil Corporation (IOC) to determine the proper infrastructure to supply the fluid.

"We are keen on shifting to CNG to bring down emission levels of our buses. It would also reduce our fuel expenditure. We had elaborate discussions with IOC, but they said they were not in a position to supply CNG now,'' reported transport official to The Times of India.

IOC executives stated they are planning the construction of an LNG terminal at Ennore. "We signed a memorandum of understanding with the Tamil Nadu Industrial Development Corporation early this month to set up a Rs 3,000-crore facility,” he added.

On behalf of Petroleum Conservation Research Association, V Sivakumar explained: "Delhi government was able to control pollution there by converting diesel-operated buses into CNG-run vehicles. Though the capital expenditure to set up the infrastructure for CNG will be high, it would give 1.5 times more mileage than diesel. It will also increase the operational efficiency of the vehicle."

LANXESS Optimistic About Tyre Market in India

LANXESS, a specialty chemicals firm, foresees increase in demand for synthetic rubber in India, a country with a long history in the production and consumption of natural rubber. Driven by the need of rapid modernization, India is currently undergoing a shift towards replacing natural with synthetic rubber in a variety of applications. As one of the world's leaders in manufacturing synthetic rubber and backed by a history of serving the Indian market for over 40 years, LANXESS is set to play an important role in this development.

One of the growth drivers for high performance rubber in India is the automotive industry. Triggered by a burgeoning middle class, demand for passenger cars and two-wheelers is rising. The automotive industry is expected to grow by about 12-14% in 2010-2012. In addition, the government has an ambitious project of expanding and strengthening the highway infrastructure of India by an estimated growth rate of 8-9%.

Increase in mobility would generate more demand for tyres. Modern radial tyres rely on high-performance synthetic rubber to achieve their superior qualities. LANXESS manufactures a wide range of rubber chemicals, high-performance rubber and technical rubber products to cater to these demands.

To be able to serve the Indian customers locally, LANXESS, the only western company manufacturing rubber chemicals in India, operates plants in Jhagadia in the state of Gujarat and, through its subsidiary Rhein Chemie, in Madurai, Tamil Nadu (polymer bound rubber chemicals are produced).

NEC Develops Advanced Bioplastic from Plant Stems and Cashew Nut Shells

TOKYO, Japan -- NEC Corporation announced the development of a first-of-its-kind durable new biomass-based plastic (bioplastic) that is produced from non-edible plant resources. The bioplastic is created by bonding cellulose^*1, a main component of plant stems, with cardanol^*2, a primary component of cashew nut shells, which achieves a level of durability that is suitable for electronic equipments and boasts a high plant composition ratio of more than 70%.

The new bioplastic characteristics are as follows:

1. Composed of non-edible plant resources: As an alternative to petroleum-based components, cellulose is the plastic's major ingredient. The cellulose, which is produced in large amounts by plants, including grass stems, etc., is modified by cardanol, an oil-like material that is extracted from cashew nut shells. Most of these stems and nut shells are abundant resources, which are often discarded byproducts of the agricultural process.



2. High plant component ratio: The use of cellulose and cardanol, both plant resources, as the plastic's primary components produces a plastic that features a high plant component ratio of more than 70%. Current cellulose based plastics include large amounts of petroleum-based additives, which results in a low plant component ratio.



3. High durability well suited for electronics: After enhancing its reactivity, cardanol is chemically bonded with cellulose, which produces a durable thermoplastic that is strong, heat resistant, water resistant and non-crystalline (short molding time), due to the bonded cardanol's unique molecular structure consisting of flexible and rigid parts.

Comparison to existing bioplastics: polylactic acid resin (PLA) and cellulose acetate (CA) based resin (According to studies carried out by NEC):

• Durability (strength & malleability): Twice the strength of existing PLA. Comparable to conventional CA resin
• Heat resistance (glass transition temperature): More than twice the resistance of PLA, approximately 1.3 times more than CA resin
• Water resistance: Comparable to PLA, approximately 3 times more than CA resin
• Molding time: Less than 50% of PLA. Comparable to conventional cellulose-based and petroleum-based plastics.

In recent years, bioplastics composed from plant resources gathered greater attention as an effective measure to reduce the depletion of petroleum resources and alleviate global warming. However, while current leading bioplastics, such as PLA, primarily use feed grains as a plant resource, the possibility of future food shortages has emphasized the importance of using non-edible plant resources to produce bioplastics.

Therefore, non-edible plant-based bioplastics have been developed using such resources as cellulose and castor oil. These cellulose-based bioplastics have conventionally been utilized in stationery, toys and household goods. However, these modified celluloses require large amounts of petroleum-based additives such as plasticizers, which results in bioplastics with a low plant component ratio and poor durability, including heat resistance and water resistance.

A polyamide resin derived from castor oil, a non-edible plant resource is also being used in electronic parts, however, there is an inadequate supply of this plant resource to expand its use and its characteristics are unsuitable for use in a variety of electronics.

However, NEC's newly developed bioplastic resolves each of these issues. Looking forward, the company will continue with research and development towards mass production of this bioplastic and improving its suitability for a wide range of electronic equipment within the 2013 fiscal year.

This newly developed bioplastic will be formally announced at The Chemical Society of Japan / Kanto Branch meeting at the University of Tsukuba on August 31, 2010.
