Non-Toxic PVC Ca/Zn Stabilizer
Calcium and zinc stabilizers are mainly white in appearance in powder, flakes and paste form. Powdered calcium-zinc stabilizer is used as the most widely used non-toxic PVC stabilizer, commonly used in food packaging, medical devices, wire and cable materials, etc.. At present, there are already PVC calcium-zinc stabilizers that can be used for rigid pipes in China.
Powdered calcium-zinc stabilizers are not as thermally stable as lead salts, and have certain lubricity, poor transparency, and easy to spray frost. In order to improve its stability and transparency, often add hindered phenol, polyol, phosphite and β-diketone and other antioxidants to improve.
