WSD plastic processing plastic products introduced in the role

      WSD plastic processing in plastic products proportional share of less than 8%, but its role in the improvement and progress of plastics processing and application performance of it is unquestioned, now an array of plastic products almost invariably reflects the plastics additives function and role. Them with resin, processing machinery, Glycrin monostearate together constitute the three basic elements calcium stearate of the world's plastics industry.

      WSD plastic processing categories and numerous different functions. Depending on the function and role, often including stabilizing additives, processing aids and functional system gives agents the three systems. With the increased development of the plastic industry, plastic resin structure, advancement and application of technical advances in molding product performance requirements, which greatly promoted the expansion of categories of plastic additives consumption and production progress.

       WSD plastic processing can be divided into "synthetic additives" and "processing aids" two systems. Synthetic additives is defined by the monomers involved in the polymeric resin during various auxiliary chemicals, such as polymerization, initiator, molecular weight modifier, the terminating agent, emulsifier,PVC heat stabilizer for window dispersing agentand antifouling agent. They are intended to improve the conditions  of the polymerization, to adjust the size and distribution of molecular weight, is closely related to the polymerization process, the polymer resin and is generally not into the plastic article, the return on such additives customary in the discussion of the synthesis resin, and statistical category is not listed as plastic additives. The basic concept in the frame of modern plastics additives given in terms of processing aids.

       Is well known, WSD plastic processing molding process with the article consists essentially of, mastication, shaping processes to complete. In this process, resin, additives, processing equipment (including mold) is an integral part of the basic elements. In contrast, the additive in plastics formulations insignificant,magnesium hydroxide flame retardant but its role in the improvement and advancement of product processing and application performance on important. We can say that after the polymer resin structure determination, selection and application of additives products is the key to the success of the decision.
