The advantage and disadvantage of Calcium Zinc Stabilizer
Calcium and zinc stabilizer
Calcium zinc stabilizers are usually divided into: solid calcium zinc stabilizer and liquid calcium zinc stabilizer.
Calcium and zinc stabilizer from the calcium salt, zinc salt, lubricants, antioxidants as the main component of the
use of special composite process and synthesis. It not only can replace lead and cadmium salts and organic tin and other toxic stabilizers, but also has a very good thermal stability, light stability and transparency and color strength. Practice has proved that in the PVC resin products, processing performance, thermal stability is equivalent to lead salt stabilizer, is a good non-toxic stabilizer.
calcium and zinc stabilizer to replace lead salt must solve the problem
Solid calcium and zinc stabilizer: calcium and zinc stabilizer appearance was mainly white powder, flaky, paste. Powdered calcium and zinc stabilizer is used as the most widely used non-toxic PVC stabilizer use, commonly used in food packaging, medical medical equipment, wire and cable materials, PVC pipe and PVC fitting products.
Powdered Ca Zn stabilizer thermal stability as lead salt, has its own a certain degree of lubrication, poor transparency, easy to spray cream and other characteristics. In order to improve its stability and transparency, often added hindered phenol, polyol, phosphite and β-diketone and other antioxidants to improve.
Calcium and zinc stabilizer two systems are divided into hydrotalcite system and zeolite system.
The price of powdered calcium and zinc stabilizer is uneven, and there is no standardized national standard to regulate it.
