  toughening agent 发现几乎 has plastics products different degree in internal stress, especially is plastics injection products internal stress more is obvious. internal stress in not only make plastics products in and use process in 出现应 force cracking and warpage deformation, effect/influence plastics products force property can, optical property can, electrical property can and appearance quality and other.

     一, toughening agent is tool has decline composite/compounding material property and composite/compounding material impact resistant function type additives. can separation is active property toughening agent and non active property toughening agent type, active property toughening agent is its separation upper can and resin active property 基团, it can formed 网络构造, add separation flexible 链, rear composite/compounding material impact resistant function. 缤纷 toughening agent 发现 non active property toughening agent is type and resin good versus solvent, 但不参 add chemical toughening agent.

     二, toughening agent 几乎都含 has active property 基团, can and resin chemical reaction, solid rear full versus 容, has also need separation versus, obtain relatively toughened 效果, make heat deflection temperature (HDT) or decline micro, impact resistant property can also obvious improvement. low separation liquid or is increase agent material add resin in, although can reduce property, rigid property, strong/high degree, heat deflection temperature (HDT) large degree decline, 暂且不 can meet/satisfy structure bonding requirements, therefore, increase agent and toughening agent is full different.

     三, 缤纷 toughening agent usually by as is increase agent film flexibility property product, generally lower, in 经 胶黏 agent rear product, it tool has relatively large property, if surface treatment, it surface 就会出现脆裂 phenomenon, toughening agent product can very good solution this issues, it is types can increase film surface tough property product, it use can improve/increase agent film flexibility property, make it in heavy upper more add 突出.
