TG series Calcium-zinc stabilizer is synthesized by a special composite process with calcium salt, zinc salt, lubricant and antioxidant as the main components. Practice has proved that the processing performance is good in PVC resin products, and the thermal stabilization effect is equivalent to the lead salt stabilizer, which is a good non-toxic stabilizer. It can not only replace toxic stabilizers such as lead-cadmium salts and organotin, but also has quite good thermal stability, light stability, transparency and tinting strength.
