Plastic additives in plastics role

Plastic additives in plastic products accounting for less than 8%, but its plastics processing and application performance to improve and enhance the role is unquestioned, now an array of plastic products almost invariably embodies plastics additives function and role. Them with resin, processing machinery constitute a plastics industry in today's world the three basic elements.
Plastic additives categories and numerous different functions. According to the function and role of different, often including stabilizing additives, processing aids and functioning agent system three systems. With the development of the plastics industry, plastic resin structure increases, molding technology and applications to improve the performance requirements for products, which greatly promoted the expansion of plastics additives categories of consumption and production increased.organic pigments
Plastic additives can be divided into "synthetic additives" and "processing aids" two systems. Synthetic additives is defined by the polymer resin monomers involved in the process various auxiliary chemicals, such as a polymerization inhibitor, initiator, molecular weight modifier, terminating agents, emulsifying agents, dispersing agents, and antifouling agents. They are designed to improve the polymerization conditions, adjust the size and distribution of the molecular weight, the polymerization process is closely related to the polymer resin and is generally not into plastic products, such additives customary synthesis of the resin normalized discussed, but also not included in the statistical category of plastic additives. Modern plastics additives to the basic concept of processing aids framed in terms.Metal stearate
As we all know, plastic molding process is essentially a tie, mastication, molding processes to complete. In this process, resin, additives, processing equipment (including mold) is an essential basic elements. In contrast, the additives in plastics formulations insignificant amount, but its effect on products processing and application performance to improve and enhance the role of pivotal. It can be said, in the polymer resin structure is determined, the aid is to determine the selection and application of products, the key to success.
