The PVC stabilizer mainly delays or stops the degradation of plastics under the action of physical and chemical factors. PVC stabilizer should have the following functions.
First of all,the PVC stabilizer can replace the active and unstable chlorine atoms in the molecule and inhibit the dehydrochlorination reaction.
Second,the PVC stabilizer can absorb or neutralize the HCl released during processing and use, and terminate its autocatalysis.
Third,the PVC stabilizer can carry out double bond addition reaction with polyolefin structure to eliminate or slow down the discoloration of products.
At last,the PVC stabilizer can capture free radicals and adsorb ionic impurities, and improve the activation energy of PVC removal of HCl.
