PVC heat stabilizer


PVC heat stabilizer is mainly used for PVC and other chlorine-containing polymers.It was found that the PVC can be processed only at above 160 ℃.It began to thermal decomposition in 120 ~ 130 ℃, release HCl gas, if not inhibit the production of HCl, decomposition and will further aggravate, this problem was the main difficulty in the development and application of PVC.


The study found that if PVC in contain a small amount of salt metal like lead the impurities such as soap, phenol, aromatic amine, does not affect the processing and application, and can have the effect of delaying its thermal decomposition to a certain extent. The above problems were solved, which led to the establishment and development of the research field of heat stabilizer.
