What are the advantages of PVC extrusion profiles compared to ABS, PE and other plastic profiles?

PVC is polyvinyl chloride. Among all plastics, the price of PVC resin powder is cheap. The advantage is that the price is cheap, the strength and toughness are better. The disadvantage is that the PVC resin powder cannot be used directly, but related additives must be added. After entering with stabilizer and auxiliary materials, products can be produced. There are special requirements for the extrusion screw and barrel. Because of the plasticization relationship, the equipment is targeted. ABS has poor weather resistance, light specific gravity, and poor chemical resistance. However, if ABS and PVC are blended and modified to produce PVC/ABS alloy pellets, the advantages of the two products can be combined and the price is cheap. PE is Polyethylene. This product has light specific gravity and is easy to process. It does not require too much screw and barrel, and has a wide processing temperature, but its hardness is not as good as that of PVC and ABS. In terms of chemical resistance, it is inferior to PVC in some places.
