PVC Resin
PVC Resin
PVC Resin
CAS NO.:9002-86-2; 93050-82-9
Molecular Formula: (C2H3Cl)n
Molecular Weight: 62.5
Property: White powder, brilliant luster. 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.
Application: Used in light industry, building material, agriculture, packaging and power fields. Also used in construction, transportation, machinery, electronics, chemical, food packaging etc,.
Packing: 25kg per bag compound with plastic, or as client’s request
Storage: Should be stored in dry and well-ventilated storehouse, and avoid direct sunlight.
