1. Different chemical name and composition
PVC material, chemical industry refers to compound PVC. Its English name is polyvinyl chloride, abbreviated as PVC; ABS plastic is a terpolymer of acrylonitrile (a), butadiene (b) and styrene (s). A represents acrylonitrile, B represents butadiene and s represents styrene. The relative content of the three monomers can be changed at will to make various resins.
2. Different characteristics
PVC material has non flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidant, reducing agent and strong acid. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contacting with aromatic hydrocarbons and chlorinated hydrocarbons.
ABS material has good low temperature impact resistance. Dimensional stability. Electrical properties, wear resistance, chemical resistance, dyeing, finished product processing and mechanical processing are better. ABS resin is resistant to water, inorganic salt, alkali and acid, insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. ABS resin has low heat deformation temperature, low flammability and poor heat resistance.
