Chemical additive PVC Calcium Zinc Heat Stabilizer

Calcium-zinc stabilizer is composed of calcium salt, zinc salt, lubricant, antioxidant, etc. and is synthesized by special composite process. It can not only replace toxic stabilizers such as lead and copper salts and organotin, but also has good thermal stability, light stability, transparency and coloring power. Practice has proved that in PVC resin products, the processability is good, and the thermal stability is equivalent to that of lead salts, so it is a good non-toxic stabilizer. In addition, the powder calcium-zinc stabilizer provides excellent thermal stability, so that PVC products can withstand high temperature without degradation. It also has good weather resistance, ensuring that PVC products can maintain their physical and mechanical properties even when exposed to harsh environmental conditions. Powdered calcium-zinc stabilizer is applied to various transparent soft and semi-hard products, and contains auxiliary stabilizer, which can provide good initial coloring and lo…
