PVC Heat Stabilizers

Because of the poor thermal stability of PVC, PVC under high mechanical shear and heat, light, oxygen will rapidly dehydrochlorinate to form conjugated polyene structures and cause darkening resin, mechanical properties decrease. It must be added the appropriate stabilizer to repair defective PVC chain, and absorb HCL PVC dechlorination generated. Heat stabilizer mechanism of action: First, to absorb the decomposition of hydrogen chloride PVC. Second, to replace or eliminate unstable chlorine atoms to keep PVC not easy to dehydrochlorinate. According to the chemical composition heat stabilizers traditionally can be classificated : lead salt, such as metallic soaps, organic tin, organic antimony, composite heat stabilizer and the liquid secondary heat stabilizer.

Our company mainly engaged in Baerlocher PVC heat stabilizers, and its products are as follows:
