Highlights at a glance
PVC chairs, particularly those made from PVC77~90170100, are not sunproof due to their poor stability against light and heat. When exposed to temperatures above 100°C or prolonged sunlight, these chairs can decompose, releasing hydrogen chloride and leading to discoloration and reduced physical properties. Explore recommended products from LYDD, including Tianjin Dagu Chemicals PVC Resin DG-800 and Rutile titanium dioxide HTR-616 to enhance durability.
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.
