Weatherseal with sealing surface having strips of material exhibiting reduced adhesion bonding to frozen water

摘要

A weatherseal has a portion of a sealing area defined by a freeze release material. The freeze release material has a lower affinity to bonding with water or ice than an adjacent area of the sealing area. The freeze release material is incorporated into the sealing portion to reduce the overall affinity of the weatherseal to ice bonding, while maintaining the desired performance characteristics of the seal including the flexibility and recovery of the sealing surface. The area of contact by the weatherseal is defined by both the freeze release material and a different material forming an adjacent portion of the weatherseal.
