Highlights at a glance

PVC chairs are not sunproof and degrade when exposed to high temperatures or sunlight. The material's stability to light and heat is poor, leading to discoloration and reduced mechanical properties. For better durability, consider products like Tianjin Dagu Chemicals PVC Resin DG-800 and Rutile titanium dioxide HTR-616.

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 â„ƒ, and the decomposition begins at about 170 â„ƒ. The stability to light and heat is poor. When it is above 100 â„ƒ 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.
