Jyco finds a way to use EPDM in extruded TPV

ERJ staff report (SS) Dexter, Michigan -- Jyco Sealing Technologies has announced that it has found a way to use reground EPDM (ethylene propylene diene monomer) in extruded thermoplastic vulcanisate (TPV) for high performance automotive weather sealing systems.

"This is a major advantage to our customers trying to build the greenest possible vehicles," said Shawn Jyawook, Jyco's chief operating officer, in a 14 Dec statement.

JyGreen requires no re-compounding, and scrap from its processing into TPV is recyclable. The TPV production process itself is free of VOCs (volatile organic compounds) and particulate emissions characteristic of EPDM processing, said Jyco.

“Until now, R-TPV (recycled thermoplastic vulcanisate) has been limited to dunnage or basic injection moulded parts like grommets, bushings, bumpers and mud flaps. With JyGreen, we can now extend the environmental and cost benefits to primary seals, glass run channel, hood and trunk lids, sunroofs and other demanding weather sealing applications," said Jyawook.

The company said that its production meets stringent environmental standards in Europe and Asia, where the company has plants in addition to their North America operations.

“Going beyond the benefits of tyre recycling, the idea that all of the weather stripping systems can eventually be stripped from the vehicle and recycled is one that we think the whole auto industry will embrace,” said Mark Steward, Jyco's material development manager, in the statement.

Founded in 2000, Michigan, US-based Jyco designs, engineers TPV and process technology for automotive, heavy truck and RV weather sealing applications.
