Polymer material is a multi-phase composite system with polymer as the main body, that is, few products are made of pure polymer, and most of them are used together with Polymer Additives. The purpose of adding polymer Additives is: 1. to meet the performance requirements; 2. to meet the molding requirements; 3. to meet the economic requirements. Polymer additives include plasticizers (DBP, DOP), phosphate esters (TCP trimethylphenyl phosphate), aliphatic dicarboxylic acids, lubricants, heat stabilizers, processing aids, reinforcing agents, toughening agents, curing agents, antioxidants, light stabilizers, fillers, solvents, foaming agents, and resistances. Propellant, coupling agent and antistatic agent.
