What is the role of PVC plastic special additives?
At the same time, stearic acid, titanate coupling agent, aluminate coupling agent, etc. are used to modify the inorganic filler to change the lipophilicity of the inorganic phase, but it does not fundamentally change the balance and compatibility of the multi-phase PVC system. Long-term industrial application shows that defects will appear:

How to choose plastic additives to better solve plastic problems
The structure of synthetic resin with similar structure is limited, and the structure of plastic additives is complicated. Not every polymer selection of plastic additives should choose varieties with similar structure, but plastic additives with similar structure and basic resin can really improve the efficacy of plastic additives and the comprehensive performance of products. For example, an antioxidant with an amide structure is 1098 used for nylon, and the stabilizing effect is much better than that of the antioxidant 1010, and the extraction resistance is also significantly better than the latter, while the antioxidant is 1098 used for polyolefin or polyester, without any advantage.
The Mechanism of Polymer Silicone Additive Surface Treatment Agent
The polymer silicone additive surface treatment agent is the introduction of anchoring groups, which ensures its firm adsorption on the surface of solid particles, and multi-position irreversible adsorption, it is difficult to desorb.
The difference between oleic acid amide and erucic acid amide
Oleic acid amide belongs to unsaturated fatty acid amide, is a white crystalline or granular solid, polymorphic structure, odorless, it can reduce the resin in the process of internal friction between the film and conveying equipment friction, simplify the operation of the final product, thereby increasing production. For example, as a lubricant for polyethylene processing, it can reduce the melt viscosity of resin particles and improve fluidity.
