What will be the development trend of stabilizers in the future

Reviewing the market in the past few years, the development of heat stabilizers is very fast, and there are the following tendencies from the general point of view:

1, high stabilization efficiency

Improve the stabilization efficiency can not only extend the service life of the product, but also improve the high temperature processability, reduce the amount of PVC stabilizers added. Especially in the development of some environmentally friendly stabilizers, the development of new organic auxiliary stabilizers, such as phosphite. It has excellent who solubility for polyolefins, polyesters and polycarbonates. In addition, there is to improve the compounding technology, create high-quality products, the development of weathering additives and light stabilizer compounding technology. Development of metal-free stabilizers, reduce metal soap, especially the use of zinc soap.

2, reduce costs

Improve the effectiveness of stabilization, can undoubtedly reduce costs, but people continue to work hard to centralize production, automation, the development of a multi-purpose excellent PVC stabilizer new varieties to reduce costs. At the same time, we should also make full use of cheap raw materials. Such as the development of antimony stabilizers instead of tin stabilizers, because of its excellent heat resistance, only a small amount of cooperation can be obtained than tin stabilizers better heat resistance.

Single its disadvantage is poor weather resistance. This needs to be overcome. Currently antimony product sales are increasing, rare earth PVC stabilizers are now the world's stabilizers in a series of rookies, and non-polluting, non-toxic, with good light, heat stability. I over rare earth resources are very rich, should strengthen the research in this area. Recent research and development of composite rare-earth PVC stabilizers, the effect is much better than a single component, and has a broad application prospects.
