Abstract
A process for forming a glass run channel composite having a thin film of ultra high molecular weight polyethylene as a sealing contact surface and an elastomeric rubber as a substrate by film transfer rubber molding and the product formed thereby.
Claims10
A molded glass run channel composite comprising an elastomeric rubber substrate having a sealing contact surface of a continuous thin film of ultra high molecular weight polyethylene wherein said thin film top surface is flush with said rubber substrate surrounding top surface to provide a glass run channel composite having an aesthetically pleasing uniform surface contour.
A molded glass run channel composite comprising:
- a) at least one preformed glass run channel strip having a thermosetting elastomeric rubber substrate including a sealing contact surface of a continuous thin film of ultra high molecular weight polyethylene;
- and
- b) a molded glass run channel having a thermosetting elastomeric rubber substrate including a sealing contact surface of a continuous thin film of ultra high molecular weight polyethylene, said molded glass run channel joined to said glass run channel strip such that the ultra high molecular weight polyethylene film of the strip and the ultra high molecular weight polyethylene film of the molded glass run channel fuse to form one continuous length of film with little or no seam lines.
