Abstract
An extruded foam product is manufactured with an integral thin coating of a different material on the surface thereof. The coating is applied to the product as part of the extrusion process and prior to foaming and expansion of the product using a co-extrusion die. The coating can have vastly different or specialized properties while having an inexpensive body portion. This co-extrusion arrangement simplifies the manufacturing of the product, and allows a very thin coating to be produced, if desired.
