Ca Zn Stabilizer for PVC SPC Wood Plastic Products

The special calcium zinc stabilizer developed for high-speed extrusion and high filling of PVC is mainly a processing raw material additive synthesized by a special composite process with calcium salt, zinc salt, lubricant, antioxidant, etc. as the main raw materials.

Product performance

1. Green environmental protection: there are no heavy metal elements (lead \ barrier), which can meet the requirements of the latest environmental protection standards of various countries (such as EU rhos directive, reach directive, etc.).

2. Resistance to vulcanization pollution: in the field of PVC door and window profiles, products using composite lead heat stabilizers are easy to pollute with sulfur and tin, resulting in blackening, while calcium zinc stabilizers are not affected by this

3. Good system switching characteristics: it can directly replace lead salt and organotin stabilizer. The conversion of traditional composite lead heat stabilizer to organotin stabilizer will cause cross contamination, and the product will turn black. Calcium zinc stabilizer will not be switched and blended at will.

4. Product characteristics: give PVC mixture good uniform plasticization and high-speed melting fluidity, and make the surface of products brighter No impurities, high-efficiency weather resistance, wide application range, less dosage, in white products, whiteness is more than its similar products.

Problems to be solved when calcium zinc stabilizer replaces lead salt

Liquid calcium zinc stabilizer is a complex of calcium zinc organic salt, phosphite, polyol, antioxidant and solvent. The liquid calcium zinc stabilizer has good compatibility with resin and plasticizer, good transparency, not easy to precipitate, less dosage and convenient use. The main disadvantages are poor lubricity, lower softening point of products, and deterioration after long-term storage.

The solid compound calcium zinc soap stabilizer is mainly stearic acid soap, followed by lauric acid soap and oleic acid soap. The product is characterized by good lubricity and does not reduce the softening point of PVC hard products. It is suitable for processing rigid PVC pipes and profiles.

The products obtained and processed by microemulsion technology overcome the above disadvantages People focus on two aspects for improvement: in order to improve the initial coloring, a sufficient amount of zinc soap is mixed, and zinc chloride is harmless by using chelating agent. This method becomes a high zinc coordination: reduce the amount of zinc soap to suppress zinc burning, and change the initial coloring with additives. This method becomes a low zinc coordination., It is not only widely used in soft products, but also successfully used in hard products processing. In order to keep the initial coloring of Ca / Zn system very small and to suppress zinc burning.

Generally, lead salt is only attached to the surface of PVC particles, and its effect is equivalent to hindering the fusion between PVC particles. It will obviously delay the plasticization, reduce the friction between PVC particles, reduce the shear effect in PVC, and the processing equipment bears low load. The more the amount of lead salt, the finer the particles of lead salt, the more obvious the secondary effect.
