Abstract
A shrinkage control material for elastomeric molding. On a surface of a resilient metal wire, an adhesive layer of a halogenated polymer-based or olefin-based adhesive is disposed. An elastomeric molding includes the shrinkage control material and a elastomeric extrusion formed around the shrinkage control material to cover, the elastomeric extrusion being bonded by vulcanization to the shrinkage control material.
Claims2
An elastomeric article for a door window glassrun channel of a vehicle comprising:
- a shrinkage-controlling portion comprising a resilient metal wire and a heat-treated adhesive layer on the metal wire;
- and
- an elastomeric portion extruded around an outer periphery of the shrinkage-controlling portion, the elastomeric portion being bonded by vulcanization to the shrinkage-controlling portion,
- wherein the metal wire is selected from the group consisting of a brass wire and a brass-plated steel wire, the adhesive layer comprises a chlorinated rubber and a chlorosulfonated polyethylene rubber, the adhesive layer is from 5 μm to 25 μm thick, and wherein the elastomeric extrusion comprises an ethylene-propylene-diene ternary copolymer.
