Description
It is a powder with characteristics of good crystallization, free flow and particle optimized,which can be used as a kind of PVC heat stabilizer mixed formulation at flexible and rigid PVC, can replace of lead stabilizer. It can significantly improve the thermal stability and anti-tarnishing ability of PVC products. It also can alternatively replace the zinc stearate stabilizers to improve the thermal stability and decrease in the production cost simultaneously.
