Classification Of PVC Heat Stabilizers
Apr 22, 2018

Generally classified according to the chemical components of PVC heat stabilizers, it can be basic lead salts, metal soaps, organic tin, epoxy compounds, phosphites, polyols, etc. According to the size of the action, the PVC stabilizer can be divided into a main stabilizer and an auxiliary stabilizer. The auxiliary stabilizer itself has little or no thermal stabilization effect, but it has a synergistic effect with the main stabilizer. The main stabilizer is generally a metal-containing thermal stabilizer. Pure organic compounds such as epoxy compounds, phosphites, and polyols are generally used as auxiliary stabilizers.
