Sliding or lip seal for motor vehicle window is made from co-extruded dynamically functional and non-functional sections of different polymers

摘要

The seal (1) is made from co-extruded polymers forming its dynamically functional (B) and non-functional (A) sections, the material of the non-functional section having a modulus of flexure below about 100 MPa and resistant to deformation at temperatures below about 90 deg C, and comprising a thermoplastic material such as a non-vulcanized polyolefin. The seal (1) is made from co-extruded polymers forming its dynamically functional (B) and non-functional (A) sections, the material of the non-functional section having a modulus of flexure below about 100 MPa and resistant to deformation at temperatures below about 90 deg C, and comprising a thermoplastic material such as a non-vulcanized polyolefin. The seal lips (11) or dynamically functional section of the extrusion are made from a different thermoplastic elastomer.
