What is polyvinyl chloride pvc do you know
Polyvinyl chloride pvc is a white powder with an amorphous structure, with a small degree of branching, a glass transition temperature of 77~90 °C, and begins to decompose at about 170 °C. It has poor stability to light and heat. It will decompose to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration, and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve thermal and light stability.
Polyvinyl chloride pvc was once the largest general-purpose plastic in the world, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.
