We usually use plastic is not a pure substance, it is made of many materials from the preparation of the. Polymer (or synthetic) is the main component of plastic, in addition, to improve the performance of plastic, also added various auxiliary materials in polymers, fillers, plasticizers, lubricants, stabilizers, colouring agents, antistatic agents, to become a high performance plastic.
Plastics additives plastic additives, polymer (resin) when carrying out processing in order to improve its machinability or insufficient performance to improve themselves, and some compounds that must be added. For example, in order to reduce the temperature of PVC resin to make products soft and add a plasticizer; and as for preparation of light weight, shock, heat insulation, sound insulation foams and foaming agent to be added; some plastic is very close to the processing temperature of thermal decomposition temperature, cannot be formed without heat stabilizers for joined. Thus, plastic additives in plastics processing plays a particularly important role.
