STABILIZER COMBINATION FOR CA / ZN-STABILIZED PVC MOLDING MATERIALS, PVC MOLDING MATERIALS AND METHOD FOR THE PRODUCTION THEREOF

摘要

A stabiliser combination for Ca/Zn-stabilised, transparent to glass-clear PVC moulding masses contains calcium salts of C8-C34-fatty acids, zinc salts of C8-C18-fatty acids, epoxidised C16-C22-fatty acid glycerides and diesters of ethylene glycol with C16-C18-fatty acids. The stabilisation obtained is comparable or superior to that achieved hitherto using cured castor oils.
