Lead Pvc Stabilizer is lead based compound PVC heat Stabilizer, containing internal and external lubricants, Have excellent processing performance for calendaring molding, it will not effect the faltness, brighten and clean.

Calcium zinc stabilizer is an additive used in plastic processing to stabilize the thermal and photostability of plastic materials. Calcium zinc stabilizers are usually composed of calcium salts and zinc salts, which can effectively inhibit the degradation and aging of plastics under high temperature and ultraviolet radiation.

The main functions of calcium zinc stabilizers include the following aspects:

1. Thermal stability: Calcium zinc stabilizers can absorb and disperse heat during plastic        processing, preventing plastic materials from decomposing and degrading at high temperatures, thereby improving the thermal stability of plastics.

2.Light stability: Calcium zinc stabilizers can absorb ultraviolet radiation, prevent degradation and aging caused by ultraviolet radiation on plastic materials, thereby improving the light stability of plastics.

3.Preventing oxidation: Calcium zinc stabilizers can inhibit the reaction between plastic materials and oxygen, preventing degradation and aging caused by oxidation reactions.

Promoting processing performance: Calcium zinc stabilizers can improve the flowability and processing performance of plastics, enhance the processing efficiency and product quality of plastics.
