Ca-Zn stabilizers are generally divided into solid Ca-Zn stabilizers and liquid Ca-Zn stabilizers.
The Ca-Zn stabilizer is synthesized by a special compound process with calcium salt, zinc salt, lubricant, antioxidant, etc. as the main components. It can not only replace toxic stabilizers such as lead, cadmium salts and organotin but also has very good thermal stability, light stability, transparency and tinting power. The practice has proved that in PVC resin products, the processing performance is good, the thermal stability is equivalent to the lead salt stabilizer, and it is a good non-toxic stabilizer.
Ca-Zn stabilizer and PVC resin have good dispersibility, compatibility, processing fluidity, wide adaptability, excellent surface finish; excellent thermal stability, small initial hue, no precipitation; no heavy metals And other toxic ingredients, no vulcanization; Congo red has a long test time, has excellent electrical insulation, no impurities, and has high efficiency and weather resistance; wide application range, strong practicability, low dosage, and versatility; in white products Among them, the whiteness is better than similar products.
According to different uses, there are different varieties of Ca-Zn composite stabilizers: CZ-1, CZ-2, CZ-3, etc., which are used for pipes, profiles, pipe fittings, plates, injection molding, blown film, cable materials and other plastic products.
