Calcium-zinc heat stabilizer
Product Title：Environmentally friendly calcium-zinc type composite heat stabilizer
product presentation：Calcium-zinc stabilizers are synthesized by a special composite process with calcium salts, zinc salts, lubricants, antioxidants and other main components. It can not only replace toxic stabilizers such as lead and cadmium salts and organotin, but also has quite good thermal stability, light stability, transparency and tinting strength. Practical experience has shown that in PVC resin products, it has good processing performance and a thermal stabilizing effect equivalent to that of lead salt stabilizers, making it an excellent non-toxic stabilizer.
