Heat and impact resistance of bioplastic significantly enhanced


Technology to significantly enhance the heat and impact resistance of a high-performance bio-polycarbonate resin has been developed by its Japanese supplier. Teijin Limited (Tokyo) has modified the molecular design of its Planext polymer to achieve greatly improved heat resistance with a glass-transition temperature of 120°C, as well as superior resistance to impact.

In addition, a separate proprietary flame-retardant technology enables Planext to achieve top-level flame retardancy of UL94V-0 at 1.6 mm. Teijin plans to develop markets for Planext as a strategic bio and next-generation transparent material with new applications in the electronics, architecture and exterior fields, starting with the Japanese market. Annual production capacity at the company’s Matsuyama Factory in Ehime Prefecture, Japan is expected to expand to 3000 tonnes within a few years....
