     PC toughening agent versus large 家都知道 toughening agent and increase agent is different, that 么我们 in separation this 两者 时候 need it what property can separation toughening agent and increase agent 呢?

 

     1, PC toughening agent in hot solid property resin and property polymer/macromolecule material in add fiber filler, can improve/increase impact resistant strong/high degree. fiber 一方面 can 承担试 sheet/slice 缺口附近 large separation negative 荷, make force dispersion to more large upper, 另一方面 also can absorption separation impact can, anti cracks expand formed 裂缝.   and versus 反, in polystyrene (PS) this 样 脆 property material in add carbon acid type powder filler, 则往往 make material impact resistant property can 进一步 decline. is filler versus 当于基体 in defect, filler pellets also has force in function, this will accelerated material bad.   in recent years in certain plastics in add a small amount of surface treatment micro fine machine pellets, 发现 别 system in, machine filler has PC resistant toughening agent function.

   

     2, toughening agent （toughener） is can increase agent film flexibility property material 质. certain hot solid property resin agent, ring oxygen resin, aldehyde resin and saturated and polyester resin agent solid rear elongation low, property relatively large, bonding 部位承受 outer force very easy generate cracks, speed expand 展, 导致胶层 cracking, resistant fatigue, can as is structure bonding use. therefore, must method reduce property, increase large tough property, improve/increase strong/high degree. can decrease low property, increase tough property, also effect/influence agent other main/primary property can material is toughening agent. toughening agent 二般都含 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, can meet/satisfy structure bonding requirements, therefore, PC toughening agent large increase agent and toughening agent is full different.
