Shortens molding cycle time by roughly half.
Co-developed MBA900H molding compound
Panasonic Electric Works Co., Ltd. and Teijin Limited announced today their joint development of a highly heat-resistant polylactide (PLA) molding compound made 80% from plant-based renewable feedstock and providing
significantly reduced molding cycle time of around half that of conventional PLAcompounds.
From this month, Panasonic Electric Works will begin selling the new material as its MBA900H PLA molding compound for use in the housings of cell phones and other mobile devices and digital consumer electronics. The initial goal is 1,000 tons of annual production by fiscal 2012 ending in March 2013.
The bioplastic used in the MBA900H is Teijin’s BIOFRONTTM, a highly heat-resistant PLA with a melting point of at least 210C, which is significantly higher than that of conventional PLA. BIOFRONTTM also shows better
hydrolytic stability and achieves semi-crystallization in just 20–25% of the time required with conventional PLA.
Panasonic Electric Works successfully developed the MBA900H molding compound using its proprietary compound-design and production technologies. The new material has been proven in testing conducted by the
company to shorten molding cycle time by roughly half compared to conventional PLA compounds.
Efforts to shift from oil-based to biomass-based plastics are increasing as companies look for ways to help protect the global environment and create sustainable societies. Bioplastics, for example, are being used increasingly in
consumer electronics, automotive interiors and other areas, but conventional PLA has low heat resistance and limited injection-molding capability because of its longer molding cycle time. Molding compounds have been developed by
mixing PLA with oil-based plastics, but attaining the desired levels of heat resistance and moldability has required a high ratio of oil-based plastic.
The MBA900H solves these problems as a molding compound that combines high biomass ratio with superior heat resistance and moldability.
Teijin will continue to accelerate its cultivation of new applications and markets for BIOFRONTTM, which already is used in clothing, interior goods, automobiles and consumer electronics. Teijin aims to mass produce some 5,000 tons of BIOFRONTTM in fiscal 2011, and then eventually several tens of thousands of tons of this advanced bioplastic.

Wij gaan ervan uit dat CSM contacten heeft met Teijin. Wij kunnen deze vermoedens niet bevestigd krijgen. Maar Teijin zegde wel haar JV (50-50) met Cragill op voor de levering van PLA's.

Teijin Chemicals Enters Electronic Paper Market with Transparent Conductive Films
Teijin Chemicals Limited, the core company of the Teijin Group's plastics business, has begun manufacturing and selling transparent conductive films that are expected to be used in new versions of electronic paper that are lighter and thinner than conventional products on the market.
Teijin Chemicals has begun selling two types of transparent conductive films: SS120, which uses polycarbonate (PC) film as substrate, and HP125, which uses polyethylene terephthalate (PET) film as substrate. The former is suited for electronic paper that uses liquid crystal and the latter is suited for electronic paper that uses electrically charged particles.
For both films, Teijin Chemicals utilizes proprietary high-precision coating technology to form the hard coating layer and vacuum coating technology to form the gas barrier layer and the transparent conductive layer.
The company boasts a fully comprehensive processing system covering every stage, from the design of products consisting of substrate and layers to manufacturing. Moreover, Teijin Chemicals manufactures PC film and Teijin DuPont Films manufactures PET film, so both substrates are produced within the Teijin Group.
Electronic or "rewritable" paper has the ability of conventional paper to display fixed information without consuming power and the ability of electronic devices to display changeable information. The market for electronic paper is expected to grow rapidly in fields including e-books, mobile phones, wristwatches, electronic tags, point-of-purchase advertising, digital signage and more.
The majority of electronic paper currently available on the market is made with glass substrate, but transparent conductive film is expected to be increasingly adopted as the main substrate of future electronic paper because it enables the production of lighter and thinner devices.
Teijin Chemicals' high-quality transparent conductive film using polycarbonate film as substrate already is used widely in touch panels. In addition to electronic paper, the film is expected to find additional applications, such as organic light emitting diodes (OLEDs). Going forward, Teijin Chemicals intends to further improve the performance of its transparent conductive film while exploring other promising new markets.
