A collaborative industrial project between the Japanese companies Teijin Limited, Teijin Chemicals and also Tanaka Foresight Inc. has allowed to develop eyeglass frame entirely made from plant-based, heat resistant poly(acid lactic) (PLA). The chosen material is a Biofront™ grade from Teijin Limited, that is said to be the world's first mass-produced stereocomplex PLA, made with plant-based Poly-L-lacticacid polymer (conventional poly(lacticacid acid)) and their enantiomer poly-D-lacticacid polymer. This highly stable stereocomplex structure, based on Teijin's polymer technology, allows to obtain a melting point of 210° C, that is over 40°C higher than that of poly-L-lacticacid polymer, putting Biofront™ heat resistance at par with oil-based poly(butylene terephthalate) (PBT). Biofront™ PLA exhibits high resistance to bleaching and antibacterial properties that suits for eyeglass applications.
