PVC granulation

PVC granulation 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, and has poor light and heat stability. 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 the stability to heat and light.
