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.

Planext is an eco-friendly bio-polycarbonate made with bio-content based on isosorbide from corn starch and other plants. In addition to excellent processability and durability, it is superior to petroleum-derived polycarbonates in terms of surface hardness (pencil hardness: H), weather and chemical resistance, and light transmission of 92%. With its newly enhanced heat and impact resistance, Planext is now reportedly an ideal material for a much wider range of applications than ever before.

Teijin also recently established a dedicated department to accelerate materials business incubation through technology acquisitions and alliances from April 1. The new Technology Alliance Development Department, established under Teijin’s New Business Development Group, will strategically grow materials-related businesses by identifying promising partners and M&A opportunities. Alliances are envisioned for undertakings ranging from R&D to business model creation.
