The plastic we usually use is not a single ingredient, it is made of many materials. The polymer (or synthetic resin) is the main component of plastics, in addition, in order to improve the performance of plastics, but also in the macromolecular compound to add a variety of auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, antistatic agent, can become a good plastic.
Plastic additive, also known as plastic additives, is the polymer (synthetic resin) in the molding process in order to improve its processing performance or to improve the performance of the resin itself must be added some of the compounds. For example, to reduce the molding temperature of polyvinyl chloride resins, a plasticizer added to soften the product, or to add foaming agent for the preparation of foam with light weight, anti-vibration, heat insulation and sound insulation; the thermal decomposition temperature of some plastics is very close to the temperature of the molding process, and cannot be formed without adding heat stabilizer. Therefore, plastic additives in the plastic molding process occupies a particularly important position.
