Abstract (en)
[origin: WO9627485A1] An extruded sheet and method of forming the sheet from recycled polymeric material having a hygroscopic component, a PVC and/or PVDC component or mixtures or blends of same, and/or a crosslinked polymeric component. The recycled polymeric material is introduced into an extruder to form a melt, and the melt is extruded through a slot die to form the sheet. Also included is an extruded foam sheet incorporating a recycled material having a hygroscopic component in an amount of about 23 percent by weight, a PVC and/or PVDC component or mixtures or blends of same, and/or a crosslinked component, and the method of recycling the material by foam extrusion.
