PVC stabilizer is a kind of chemical additives with stable PVC physical and chemical properties, which can effectively improve the performance and service life of PVC products. In this paper, the knowledge of PVC stabilizer will be introduced in detail from three aspects: the mechanism, production process and application field of PVC stabilizer. The mechanism of action of

PVC stabilizers
The mechanism of action of
PVC stabilizers is mainly by absorbing or dispersing harmful substances to maintain the stability and weather resistance of PVC products. In general, PVC stabilizers are divided into organic tin stabilizers, calcium and zinc stabilizers, ester stabilizers, sulfide stabilizers and other types, of which the most commonly used are organic tin stabilizers and calcium and zinc stabilizers. The mechanism of

organotin stabilizers is to combine with PVC molecules and absorb active chlorine atoms to avoid the self-catalytic decomposition reaction of PVC molecules, thereby maintaining the performance and life of PVC products.

calcium and zinc stabilizer forms a metal film layer by reacting with the surface of PVC molecules, and prevents the thermal decomposition reaction of PVC molecules to play a stabilizing role.

and ester stabilizers and sulfide stabilizers, respectively, by absorbing impurities and the formation of PVC chlorine atoms, to avoid the degradation of PVC molecules, thereby protecting the quality of PVC products. The production process of

PVC stabilizer
The production process of
PVC stabilizer mainly includes two stages: synthesis reaction and subsequent treatment. In the synthesis reaction stage, the stabilizer base material is prepared by the reaction of raw materials such as organometallic substances and solvents, and then in the subsequent treatment stage, through further formulation and processing, various types and specifications of PVC stabilizer products are obtained.

At present, the production technology of PVC stabilizers has been greatly developed. It has not only made great improvements in the selection of raw materials, but also introduced new manufacturing processes to improve production efficiency and product quality. The application field of

PVC stabilizer

PVC stabilizer is a kind of chemical additive widely used in the production and processing of PVC products, which can significantly improve the various properties of PVC products. Therefore, PVC stabilizers have become one of the necessities for the production and processing of PVC products in all walks of life.

Specifically, PVC stabilizers can be used in the manufacture of PVC pipes, PVC wires, PVC plastic boxes, PVC furniture and other PVC products. In addition, PVC stabilizers are also widely used in construction, medical, automotive, electronics and other industries. By introducing the mechanism, production process and application fields of PVC stabilizers,

believe that readers have a deeper understanding of PVC stabilizers. We look forward to the continuous upgrading of PVC stabilizer production and application technology in the future, which will bring more convenience and improvement to our production and life.
