WEATHERSTRIP AND A MANUFACTURING PROCESS THEREFOR

摘要

A weatherstrip has a body portion including integral seal members, and a layer of a reactive urethane hot melt resin composition. The reactive urethane hot melt resin composition comprises urethane prepolymer and an additive. The weatherstrip has high abrasion resistance. Further, a method of producing the weatherstrip comprises the steps of extruding elastomeric material for the weatherstrip, and supplying the reactive urethane hot melt resin composition and simultaneously applying same to a predetermined area of the extruded weatherstrip so that a layer of reactive urethane hot melt resin composition is formed thereon.
