Sarlink TPV saves weight and cost in roof sealing for new Byd model M6

Replacing the EPDM thermoset rubber often used in exterior automotive seals, the seals produced from Sarlink TPV weigh 25% less, saving a total of 0.15 kg per vehicle, according to Teknor Apex's business development manager Ting Wang. He also cited the economic and environmental advantages of using a thermoplastic: "A key reason why Sarlink TPV has been replacing EPDM is that it eliminates the labor- and energy-intensive vulcanization step required in the processing of thermoset rubber," said Wang. "Another important advantage is the recyclability of both process scrap and finished components."The seals were in development for two years in a cooperative program between Byd and the Shanghai-based Sarlink TPV team, noted HongQing Wang, technical service specialist for Sarlink TPVs, who added that the project represented the first TPV sealing application for Byd."The Sarlink group not only supplied us with high-quality materials but also provided us with information on TPV application, including positive and practical advice on tooling design, the extrusion process, and the production line," said Hou Zheng-yu, manager of the production department at Byd's rubber operation.
