Two-part coated foam structure |
摘要 |
A foamed polyethylene product has an outer sheath of non-foamed polyethylene fused to an underlying foamed body portion. Preferably, the product is produced in an in-line method when the foam body is extruded and subsequently the skin is extruded directly on the body portion. This process only causes limited thermal degradation of an outer layer of the body portion which improves adhesion of the skin to the body portion.
