    toughening agent generally has active property 基团, can and ring oxygen resin reaction. solid rear full versus 容, has also need separation versus, obtain relatively toughened 效果, make heat deflection temperature (HDT) decline micro, impact resistant property can also obvious improvement. increase agent although can reduce property, rigid degree, strong/high degree, heat resistant property large decline, therefore, toughening agent and increase agent modified versus very large. has type high poly material, thermoplastic property resin, combined formed 橡胶, thermoplastic property elastomer has active property 基团, can and solid reaction, improve/increase impact strong/high degree, heat deflection temperature (HDT) and rigid property has decline, and toughening agent has 别, this material by is increase agent. tube/pipe toughened mechanism and different, has can meet/satisfy structure bonding need, 故习惯 upper will increase agent and toughening agent versus 提并论.

 

     一, different plastics （如PC,ABS,PBT,PET,PA,PPO,PP and other ） use toughening agent type type is has 差异 （ from most combined degree upper 讲）, or has toughening agent can use in more plastics in toughened, is from property ratio upper 不一定适 combined, has toughening agent is 根本不适 combined application in types plastics. this very good understanding. certain plastics can use multiple toughening agent product, 但 起 to function is has 差异, or certain plastics can use types toughening agent is toughened can, from fine degree 考虑, 我们应该想想 is is combined use in most 适当 方. this has or has 忽略思考.  

 

     二, plastics toughening agent tough property is resistant outer impact force can force, commonly used impact strong/high degree large small table/sheet 示.     impact strong/high degree is Sample to impact bad fracture 时, mono 位面积 upper consumption 功. it can used for evaluation toughening agent material property or tough property strong/high degree, material impact strong/high degree high, its tough property good; 反之说明材 material property large.
