Extrusion

Fiber-reinforced thermoplastic shapes are now being extruded, as well. Breakthrough material and process technology has been developed with long-fiber glass-reinforced thermoplastic (ABS, PVC or polypropylene) composites to provide profiles that offer a tough, low-cost alternative to wood, metal and injection-molded plastic parts used in office furniture, appliances, semi-trailers and sporting goods. A huge emerging market is extruded thermoplastic/wood flour (or other additives like flyash) composites, used to simulate wood decking, siding, window and door frames and fencing.
