PVC resin, also known as polyvinyl chloride resin, is a thermoplastic polymer material polymerized from vinyl chloride monomer. Its chemical structural formula is – (CH ₂ – CHCl) ₙ -, which has excellent chemical corrosion resistance and electrical insulation properties. However, it is inherently brittle and its impact resistance and other properties are often improved by adding modifiers

Usage: PVC resin is the most widely raw material used in plastic production. It has good chemical stability, corrosion resistance and water resistance. It can be dissolved in acetone, hydrochloric ether, ester and some alcohol. It can offer good solubility, good electrical insulation, thermoplasticity and membrane forming capacity.
