PVC is a white powder with amorphous structure. The glass transition temperature is 77~90°C, and it begins to decompose at around 170°C. After 100°C or above, it will decompose to produce hydrogen chloride and further autocatalyze decomposition to cause discoloration. Physical and mechanical properties are also rapidly declining, and stabilizers and other additives must be added in practical applications to improve heat and light stability.
