Pure white heat stabilizer for PVC solid calcium zinc stabilizer for PVC pipe
Product Features:
Calcium-zinc stabilizers are synthesized by a special compounding process using main components such as calcium salts, zinc salts, lubricants and antioxidants. It can not only replace toxic stabilizers such as lead and cadmium salts and organotins, but also has good thermal stability, light stability and transparency and tinting strength. Practice has proved that in PVC resin products, the processing performance is good, the heat stability is equivalent to the lead salt stabilizer, and it is a good non-toxic stabilizer.
The appearance of the calcium-zinc stabilizer is mainly white powder, flake, and paste. Powdered calcium-zinc stabilizer is used as the most widely used non-toxic PVC stabilizer, and is commonly used in food packaging, medical equipment, wire and cable materials, etc. At present, PVC calcium-zinc stabilizers for rigid pipes have appeared in China.
The thermal stability of powdered calcium-zinc stabilizer is not as good as that of lead salt. It has certain lubricity, poor transparency and easy to spray. In order to improve its stability and transparency, antioxidants such as hindered phenols, polyols, phosphites, and β-diketones are often added to improve.
