PVC material is a kind of plastic decorative material and is the abbreviation of polyvinyl chloride material. PVC resin is a thermoplastic polymer polymerized from Vinyl Chloride Monomer (VCM). It is made of polyvinyl chloride resin as the main raw material, adding appropriate amount of anti-aging agent and modifier, and through mixing, calendaring, vacuum suction and other processes. PVC is an amorphous polymer, containing 5% - 10% crystallites (melting point 175 degrees). The molecular weight, crystallinity, softening point and other physical properties of PVC vary with polymerization conditions (temperature). PVC resin is used as the base material, mixed with a variety of additives such as stabilizers, plasticizers, fillers, colorants and modifiers, and plasticized and molded to form PVC resin plastic. PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, simple construction, etc. There are many specifications, colors, patterns and rich decorations, which are widely used in production and life. For example, PVC pipes, PVC plastic doors and windows, as well as PVC - containing plastic toys, wires and cables. Due to its harm to human body, countries such as Europe, Japan and South Korea have imposed restrictions on products made of PVC. The outstanding advantages of common PVC resin plastic products are flame retardant, wear resistant, chemical corrosion resistant, and low leakage of gaseous water vapor. In addition, comprehensive mechanical energy, transparency of products, electrical insulation, heat insulation, noise elimination and shock elimination are the most superior general-purpose materials in terms of energy price ratio.
