Features of PVC

PVC: It is one of the plastic products with the largest output in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. According to different uses, different additives can be added, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products. The density of pure PVC is 1.4g/cm3, and the density of PVC plastic parts with plasticizers and fillers is generally 1.15-2.00g/cm3. Rigid PVC has good tensile, bending, compressive and impact resistance properties, and can be used alone as a structural material. The softness, elongation at break, and cold resistance of soft PVC will increase, but the brittleness, hardness, and tensile strength will decrease. Polyvinyl chloride has good electrical insulation properties, can be used as a low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCL gas, and make polyvinyl chloride discolor, so its application range is narrow, and the operating temperature is generally between -15 degrees to 55 degrees.
