PVC Ca Zn Heat Stabilisers

Product Description

Low Volatility PVC Ca-Zn Stabilizer

Product Features:

Calcium-zinc stabilizers are synthesized by a special compounding process using main components such as calcium salts, zinc salts, lubricants and antioxidants. It can not only replace toxic stabilizers such as lead and cadmium salts and organotins, but also has good thermal stability, light stability and transparency and tinting strength. Practice has proved that in PVC resin products, the processing performance is good, the heat stability is equivalent to the lead salt stabilizer, and it is a good non-toxic stabilizer.

  • The melting effect can be improved while with toughening, lubrication, good flowability and no precipitation.
  • Non-toxic and environmentally friendly product with no harmful heavy metal, can replace lead stabilizer, meet the ROHS standard.
  • Improve the outdoor use effect, appearance and the performance of product.
  • Excellent thermal stability.

What is stabilizer in plastic?
Stabilizers are a class of chemical additives commonly added to polymeric materials, such as plastics, to inhibit or retard their degradation. ... Degradation of plastics can cause discoloration and embrittlement. Stabilizers counteract these processes.
Which of the following are used as PVC stabilizer?
Barium-zinc additives are very effective heat stabilizers for PVC but are restricted for medical applications in some countries. Alternatives like calcium-zinc formulations are often used to stabilize medical-grade PVC against heat.
