calcium zinc stabilizers for pvc
Heat stabilizers are substances used to increase the thermal stability of polymeric materials that can undergo thermal degradation of non-chain breaks. Such as PVC, PVDC, CPVC, PE, SBR, CPE, etc. Lead salt heat stabilizer is the first heat stabilizer for PVC and is still one of the main stabilizers for PVC resin. QY-298 is a white flake solid with white pigment properties, high coverage and good weatherability. The main component of Gihug Heat Stabilizer QY-298 is lead acid and lead acid lead with unsalted lead monoxide. They all have a strong ability to combine hydrogen chloride, and there is no promotion or inhibition for the reaction of PVC dehydrochlorination. Therefore, it is widely used as a trapping agent for hydrogen chloride.
1)Good initial colour:
2) Excellent long-term heat stability and self-lubrications
3)Good processability and compatibility,
4) No dust pollutions
