Processing aid is a play a supporting role in the matter, generally have filter aid, clarification, adsorption, lubrication, stripping, bleaching, peeling, solvent extraction, fermentation with nutrients like.
Processing aid in the development and application process, according to the product ingredients be divided into the following broad categories: methyl methacrylate acrylate copolymer, styrene copolymer, acrylonitrile / styrene, etc., currently used the largest, the best is acrylate copolymer.
PVC processing aid is a very special thermoplastic resin processing its pure Processing aid , poor mobility, low impact strength, poor weather, and therefore need to add all kinds of supplementary material in the process to improve its performance. Such as: lubricants, heat stabilizers, impact modifiers, processing aids and the like.
With the development of PVC industry, especially plastic profile and the rapid development of plastic pipe industry, the demand for processing aid is also growing rapidly.
Processing aid primary role is: to Processing aid
the process of PVC plastics, improving the rheological properties of the thermoplastic melt, improve the mechanical properties of the melt under the heat elastic state. Integrated functions such as improving the appearance of quality products. Although the addition amount of the processing aid, but the processing performance is improved PVC is very important.
Although domestic product has certain geographic and price advantage in the market competition, but compared with foreign products have a certain gap in our product performance, variety, stability, etc., which is our product formulation, processing technology (such as automation control and continuity of production control), processing equipment, and related post-processing technology behind. To this end a number of enterprises in the industry is fully aware of these problems, have established partnerships with research institutions, the establishment of research institutions to carry out research on plastic additives.
