PVC chair is not sunproof. PVC is a white powder without regular structure, it has small branching degree, the glass transition temperature is 77~90 , and the decomposition begins at about 170 . The stability to light and heat is poor. When it is above 100 or exposed to the sun for a long time, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration, and the physical and mechanical properties will also decline rapidly.
