Classification: Products
Product Details
Properties
* Lubricating processing aid is a kind of low molecular weight product with a certain molecular weight distribution, which is obtained by one or several acrylate monomers synthesized through lotion polymerization process, and special molecular weight regulator is added in the lotion polymerization process, so that it has good internal lubrication performance.
* The biggest advantage of lubricating processing aids is their good compatibility with PVC resin, which can completely replace various internal lubricants with poor compatibility with PVC resin. Lubricating processing aids have both external sliding and processing properties, and their acrylic processing can provide both external sliding performance and avoid the problem of poor compatibility caused by lubricants. At the same time, they provide excellent plasticizing and additive properties, significantly improving the quality of PVC products, shortening processing time, and improving production efficiency.
