LOW FLEXURAL MODULUS PATTERN ON EXTRUDED LOW-FRICTION MATERIAL

摘要

A composite structure finds particular use as a weatherstrip on a motor vehicle. The weatherstrip includes a first material such as rubber, EPDM or thermoplastic that exhibits flexibility, and a second, hard, low friction material applied over portions of a surface of the rubber. In a preferred arrangement, the low friction material is coextruded with the first material in spaced rows that allow the weatherstrip to flex in regions where no second material is applied. An increased thickness of low friction material is applied thereby improving wear characteristics without impacting flexibility.
