BX Calcium Zinc Heat Stabilizer

Introduction – What is PVC Stabilizer?

When PVC is at 100-150°C, ultraviolet light, mechanical force, oxygen, ozone, hydrogen chloride, and some active metal salts and metal oxides will accelerate the decomposition rate on the basis of its own decomposition.

For the processing of PVC, thermal decomposition does not change its properties much, mainly affecting the color of the finished product, and adding heat stabilizers can inhibit the initial colorability of the product. In addition, if there is oxygen in the thermal decomposition process of PVC, there will be colloidal carbon, peroxide, carbonyl and ester-based compounds. In this case, it is necessary to add a heat stabilizer in the process of PVC processing, so that to a certain extent, it can replace the unstable chlorine atoms in PVC, absorb hydrogen chloride, and undergo addition reactions with unsaturated parts. Inhibits the degradation of PVC molecules.


Calcium Zinc Heat Stabilizer

Calcium Zinc Heat Stabilizer is the second largest heat stabilizer after lead salts in dosage, although its thermal stability is not as good as that of lead salts, it also has lubricity. It is non-toxic due it does not contain Cd and Pb. Non-Pollution, so it is widely used in soft PVC, such as non-toxic, transparent and so on. Metal soaps can be metal (lead, barium, cadmium, zinc, calcium, etc.) salts of fatty acids (lauric acid, stearic acid, naphthenic acid, etc.), among which stearate is the most commonly used, and its thermal stability ranking as following: zinc salt > cadmium salt > lead salt > calcium salt/barium salt. Metal soaps are generally not used alone, and are often used between metal soaps, or in combination with lead salts and organic tin.
