Teijin Develops Formable Gasoline-resistant Bioplastic Film for Vehicle Door Handles Integrated with Smart-entry Systems
Tokyo, Japan, February 14, 2018 --- Teijin Limited announced today that it has developed a formable gasoline-resistant film made of PLA NEXT® bioplastic to replace chrome plating, w hich Honda Lock Mfg. Co., Ltd. has now adopted for nonconductive door handles integrated w ith smart-entry systems. Teijin developed the innovative film using a special metal-evaporation technology from a processing-manufacturer partner.
Teijin is currently developing other automotive applications in addition to mass producing the film for door handles.

This new film is made with PLANEXT® SN4600, an improved grade of Teijin's PLA NEXT® bioplastic, w hich is made from a bio-origin chemical compound called isosorbide. In addition to original PLANEXT® properties such as chemical resistance, transparency and surface hardness, polymer reforming is used to give PLANEXT® SN4600 important new properties including gasoline resistance, formability, UV resistance.
Teijin's gasoline-resistant film is ideal for vehicle doors, which of course have the possibility of coming into contact w ith gasoline. Optimized heat resistance and filming technology enable high formability for fashioning into complicated shapes. UV protection helps to shield the base material and prevent discoloration.
Vehicle door handles are increasingly being integrated w ith secure smart-entry systems that enable doors to be locked and unlocked by simply placing one's hand on a handle sensor. The material surrounding the sensor, how ever, must be nonconductive to avoid sensor malfunctions, so conventional door handles made of electroconductive chrome plating coated on a resin base are not suitable. Plastic films made w ith a metal-evaporation process are nonconductive and already being used as metal substitutes for automotive exteriors, but they are not suitable for door handles becausethey are neither gasoline resistant nor highly formable.
Teijin w ill showcase its innovative new film at 3Decotech Expo 2018 in the Booth 3R-09,
East hall 2-3, operated by Kohki Co., Ltd. at Tokyo Big Site fromFebruary 14 to 16.
