TOKYO--(BUSINESS WIRE)--Teijin Limited announced today that it will unveil the world’s-first polycarbonate-resin pillar-less automotive front window, installed in the Tommykaira ZZ electric vehicle (EV) produced by GLM Co., Ltd., during Automotive Engineering Exposition 2017 Nagoya from June 28 to 30.
GLM, an EV manufacturer launched by Kyoto University, expects to acquire street-ready certification for the Tommykaira ZZ fitted with Teijin’s PC-resin window, after which it will offer the window as a special equipment for the car from this autumn.
PC resins are prohibited from use in automotive front windows due to safety standards. Teijin’s PC-resin window, however, thanks to its high resistance to abrasion and weather, meets new Japanese standards that will become effective in July, paving the way for its use in the Tommykaira ZZ.
Teijin also will market its PC-resin window for automakers in the U.S. and the EU, where demands are increasing for PC-resin products that meet new safety standards.
Teijin, by thickening the perimeter of its PC-resin window, has managed to eliminate the need for the A-pillar. As a result, the transparent PC-resin window achieves unobstructed sight lines for safer driving and more enjoyable sightseeing. The integrated PC-resin pillar-less window also is 36% lighter in weight than an equivalent conventional front window with an A-pillar.
Teijin already provides PC-resin solutions for plastic glazing, including for train and automotive applications, leveraging PC resin’s competitive advantages over glass, including 200 times greater resistance to impact and just half the weight. In March, Teijin developed a new plasma enhanced chemical vapor deposition (plasma CVD) hard-coating technology.
Japan’s new automotive safety standards will require plastics-glazed windows to offer enhanced resistance to abrasion and weather in vehicles models released from July. Simultaneously, PC resin will become available for automotive front windows.
