PVC stabilizer is non-toxic and multifunctional

The development of PVC stabilizers has brought a lot of convenience to our lives. The research and development of each additive will lead to PVC products that affect our lives. The PVC material is polyvinyl chloride, which can be seen everywhere in life. Pipe fittings, oil pipelines, centrifugal pumps and blowers, etc. The rigid board of PVC is widely used in the chemical industry to make the lining of various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the manufacture of plugs, sockets, switches and cables in the electrical and electronic industries. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather. These PVC products affect all aspects of our lives.

The increase in demand for PVC products drives the development of the PVC stabilizer industry. PVC products affect our lives, so the development of PVC stabilizers is getting closer and closer to life and affects life. Industrial development The PVC stabilizer industry is also developing rapidly. The development trend of additives is also towards non-toxicity, multi-functionality, compoundability, molecular weight, compound additives and rapid progress in containerization technology.

The development and research of PVC stabilizers tend to be non-toxic and non-polluting. The development and research of alternatives to Cd and Pb stabilizers are very active. The Ba-Zn, Ca-Zn and other composite metal heat stabilizers and organic The varieties of tin and organic antimony stabilizers are rapidly developed and consumed in large quantities; vitamin E has been put into practical use as a "green" antioxidant for polyolefins, and is expected to become a substitute for BHT in the future.

The trend of multifunctionalization of additives

Great progress has been made in the development of multifunctional additives. Antistatic plasticizers, flame retardant plasticizers, and multifunctional stabilizers have all come out.

PVC stabilizer compound additives and containerization trend

According to the principle of synergy between various additives, the combination of additives into one is helpful for convenient plastic processing and full automation. Compound products mostly appear in the application system of hindered phenol main antioxidant and phosphite auxiliary antioxidant, while containerized additives are mainly used in the field of PVC processing.

High molecular weight trend of PVC stabilizer

The development progress of stabilizing additives, plasticizers, flame retardants and other varieties reflects this trend. In terms of stabilization aids, the high molecular weight hindered amine light stabilizer with a high molecular weight of 150 also shows the effect of resisting thermal oxidation, the high molecular weight plasticizer has the resistance to extraction; the heat resistance and the compatibility with the resin of the high molecular weight flame retardant are obtained. improved.
