Les dernières publication autour des bioplastiques

On retient deux publications très intéressantes sur les mélanges à base de PLLA ainsi que plusieurs études sur les vieillissements de composites biosourcés. Enfin, une étude intéressante sur la compatibilisation par trans-estérification.

Brand New Cellulose Film Production Line at Innovia Films’ Wigton Site

The €10 Million investment for this new machine was agreed two years ago and will replace two existing production lines which have been in operation since the late 1940’s. The project, which was predominantly designed, built and project managed in-house, was completed on time and on budget.

Commercial Use of Renewable-sourced Merquinsa’s Pearlthane ECO in Ski Goggles from SMITH OPTICS

Merquinsa’s renewable-sourced Pearlthane® ECO, Bio Thermoplastic Polyurethane Elastomers (Bio TPU) can now be found in market leader, Smith Optics’ new Evolve collection of snow goggles. Merquinsa’s Bio TPUs are renewable-sourced (bio-content from 20% up to 90% according to ASTM D6866) and recyclable materials with properties very similar to petrochemically-based TPU, contributing to global warming reduction.

Cereplast expands with green foam development

Bio-based plastics developer Cereplast has launched what it describes as a breakthrough bio-based foamable resin that can compete with Styrofoam and other foamable petroleum-based resins.

JAPANS’ TEIJIN BOOSTS WATER RESISTANCE OF BIOPLASTIC

Japanese company Teijin Ltd. (TSE:3401) has improved the characteristics of its Biofront brand of bioplastic material, increasing the substance’s resistance to hydrolytic degradation sevenfold.
Biofront is a heat-resistant type of bioplastic derived from corn that can be processed into fibers and resins. Mazda Motor Corp. (TSE:7261) uses the material for the seats and interiors of its hybrid cars.

But with the improved water resistance, Biofront can now also be used for parts in the engine compartment as well as for office equipment and other products that require heat- and humidity-resistant materials.

According to Teijin, the modified Biofront lasted 10 times longer than regular bioplastics and seven times longer than unmodified Biofront in tensile strength experiments when subjected to an environment of 80 degrees celsius and 95 per cent humidity.
