Preparation and Performance Study of Heat Stabilizers for PVC
In order to improve the thermal stability of PVC,the heat stabilizer PU for PVC was studied.Three types of PU were prepared using different raw materials,and the products were tested.18 performance experimental samples were prepared and analyzed using Congo Red method and thermal aging method.It was proved that PU can serve as an auxiliary heat stabilizer for calcium zinc composite heat stabilizers to improve the thermal stability of PVC.This indirectly verified the good performance of PU,providing theoretical and experimental support for subsequent practical applications.
