Product Description

PVC stabilizer is one of the indispensable main auxiliaries in PVC processing. The dosage used in PVC products is small, but its effect is huge. The use of heat stabilizer in PVC processing can ensure that PVC is not easy to degrade and relatively stable. Heat stabilizers commonly used in PVC processing include basic lead salt stabilizers, metal soap stabilizers, organotin stabilizers, rare earth stabilizers, epoxy compounds, etc. The degradation mechanism of PVC is complex, the action mechanism of different stabilizers is different, and the stability effect is different.

 

The thermal degradation of PVC has a great influence on the properties of the materials. Adding heat stabilizer can delay the degradation time of PVC or reduce the degradation degree of PVC. The main functions of heat stabilizers are to replace the unstable chlorine atom, absorb hydrogen chloride, and react with the unsaturated part to inhibit the degradation of PVC molecules.

 

PVC stabilizer,it can be classified as basic lead salt, metal soap, organotin, epoxy compound, phosphite, polyol, etc. According to the action size, PVC stabilizer can be divided into main stabilizer and auxiliary stabilizer. The auxiliary stabilizer itself has little or no thermal stability effect, but it has synergistic effect with the main stabilizer; the main stabilizer is generally a heat stabilizer containing metal. However, pure organic compounds such as epoxy compounds, phosphite esters and polyols are generally used as auxiliary stabilizers.
