ABSTRACT:
A polymeric sealing/spring strip and method of producing same. The polymeric sealing/spring strip of the present invention has several various embodiments which are based upon the incorporation of silicone rubber. Some of the embodiments are based on the formation of a resilient silicone rubber surface to provide a sealing/spring contact with an opposing surface. Other embodiments of the invention incorporate the silicone rubber in such way as to utilize its resilient properties to produce a sealing/spring strip which has improved mechanical resilience properties.
The method of the present invention allows the production of a sealing/spring strip in accordance with the present invention by using extrusion techniques.
