Abstract
An extruded, low friction weather seal is disclosed which in transverse cross section consists of a semirigid base member of polypropylene, a tubular sealing member of thermoplastic elastomer, and a thin film of polypropylene or a blend of polypropylene and thermoplastic elastomer capping all or part of the tubular sealing member. The thermoplastic elastomer enables the tubular sealing member to be resilient and compliant over a wide range of temperatures, including extremely cold conditions, but has a high friction surface which is subject to wear particularly where there is relative sliding movement between the weather seal and surface to be sealed. The polypropylene thin film cap provides a low friction contact surface without adversely affecting the resilience and compliance of the tubular sealing member.
