Co-extruded Rubber Pinchweld Seal Strip for Door & Window

Introduction:

Rubber Coextrusion profiles are mainly composed of EPDM rubber foam composite made with dense, containing a unique metal fixture and the tongue-shaped buckle, durable, good for installation.

EPDM rubber seal with excellent aging resistance, high temperature resistance and chemical resistance properties of chemical agents, has good flexibility and resistance to compression set resistance, long-term use will not crack or deform, at -50 degrees to 120 degrees between can maintain its original high sealing performance.
