PVC calcium zinc stabilizer formula of the main materials are:calcium stearate,zinc stearate,B dione,phosphite ester,antioxidant,hydrotalcite,PE wax,OPE,EBS.
According to the production of different powder composite calcium and zinc,choose slightly different raw materials,such as powder composite calcium and zinc generally use phosphite esters of powder class,mainly powder raw materials.Production of liquid calcium and zinc generally choose liquid phosphite ester,mainly liquid raw materials.
In the field of transparent PVC products,calcium and zinc belong to the heat stabilizer with good environmental performance,but the general powder class used for transparent products will affect the transparency,and the heat stability effect of liquid class can not reach the heat stability effect of organic tin.Therefore,it is used more in the soft PVC field.Jiangxi Hongyuan Chemical Co.,Ltd.is a PVC calcium zinc stabilizer manufacturer,independent research and development production of PVC calcium zinc environmental protection compound stabilizer.Rare earth multifunctional heat stabilizer and PVC ultra-permeable processing AIDS are mainly used in the production and application of PVC pipe fittings,foamed boards and various PVC profiles and plates,filling the gap of environmental protection of PVC products in the industry.
