WEATHERSEAL HAVING A CONTACT LAYER WITH A PARTICULATE COATING PROVIDING A REDUCED COEFFICIENT OF FRICTION

摘要

A weatherseal is disclosed having a substrate and a thermoplastic contact layer, wherein a multitude of surface particles are disposed on the surface of the contact layer. The weatherseal is formed by extruding the substrate and the contact layer to retain the surface of the contact layer in a partially molten state. The multitude of surface particles are then impacted with the molten surface of the contact layer to adhere to the contact layer thereby forming a coating.
