    摘要: A composition for forming a reinforced composite siding product and a composite siding product formed by an extrusion process utilizing the composition is provided. The mixed resin formulation utilized to form the composite siding product includes a polymeric resin, a filler, a processing aid, at least one lubricant, and a thermal stabilizer. In a preferred embodiment, the polymer resin is polyvinyl chloride and the filler is talc. The mixed resin formulation may be extruded with a reinforcement material in a screw extrusion process to form a composite siding product. One or more reinforcing fibers may be utilized in the extrusion process. The reinforcement fibers may be present in the final product in an amount up to 25% by weight of the final product. In at least one preferred embodiment, the reinforcement fibers are glass fibers. A weatherable cap may be co-extruded to form the final reinforced, foamed composite siding product.

    摘要: A method for incorporating wet use chopped strand glass (WUCS) in a screw extrusion process is provided. A polymeric resin is added to an extruder in a polymer feed zone and conveyed to a first compression zone where the resin is at least partially melted. The molten resin is conveyed to a high volume zone where WUCS fibers are added. In the high volume zone, the flights of the screw may have a greater pitch to facilitate the introduction of the WUCS into the extruder. The molten resin/fiber mixture is conveyed to a second compression zone where the resin and fibers are intimately compounded. Next, the molten resin/fiber mass is conveyed to a low pressure zone where moisture evaporated from the fibers is released through an opening. The resin/fiber mixture is then conveyed through a compression/die feed zone to further compound and mix the resin and fibers.
