toughening agent 认 is resin although is plastics in main/primary formed separation, is mono pure resin 往往不 can meet/satisfy molding production in process requirements and molding rear use requirements, must in resin in add 一定数 amount additives, through this additives improvement plastics property can.

     （1） plastics additives function classification has relatively large use property, 便于阐述也利于 selection. generally will plastics additives separation is processing additives, strong/high degree additives, lifespan additives, surface additives, optical 助刑, additives, its it additives large type.

     （2） plastics in main/primary necessary formed separation is resin, resin has resin and combined formed resin, plastics large more using/adopting combined formed resin. toughening agent combined formed resin is will low separation combined material mono through combined formed methods production polymer/macromolecule combined material, it versus for separation quality generally large 于1万, has can to 百万, therefore will it is polymer or high poly material.

     （3） strong/high degree additives is can left right plastics strong/high degree material 质, increase agent, toughening agent, reinforcement agent. toughening agent processing additives is that has resin molding processing material 质, heat stabilized agent, inner outer lubricant, processing modifier, demolding agent and other, is can 够改变 resin processing features make its processing additives.
