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
found in 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 Qihong
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. In addition, QY-298 has
the following advantages:
- Good thermal stability, Yang is especially good for long-term heat
- Good electrical insulation, can be used to make cable materials
- Active agent as a foaming agent
- High quality and low price
