PTFE/FIBERGLASS COMPOSITE FOR USE AS A CONVEYOR BELT

摘要

A PTFE/fiberglass composite for use as a conveyor belt comprises a fiberglass fabric having oppositely facing surfaces. The fabric has a structure defining a substantially uniform pattern of openings extending from one to the other of its major surfaces, with the average area of the individual openings being at least about 0.20258mm2. PTFE films are laminated to the major surfaces of the fabric. The laminated films are interconnected by fluroropolymer ties extending through the fabric openings and are adhered to the major surfaces with a peel strength of between about 5- 13 pli. The composite has a thickness of less than about 20 mils and a fiberglass content of less than about 25%,
