   PBT toughening agent from upper toughened and increase different, toughened it make material overall 柔化, is will ring oxygen resin solid material versus system formed more versus system, toughening agent poly formed pellets in ring oxygen resin crosslinked 网络构 formed versus in formed dispersion versus, resistant cracking property can 发生突变, fracture tough property significantly improve/increase, force property can, heat resistant property loss relatively small.

     A- PBT toughening agent is different type type toughening agent, has different toughened mechanism and 效果. liquid poly 硫橡胶 can and ring oxygen resin reaction, 引入一部 separation flexible 链段, reduce ring oxygen resin modulus, improve/increase tough property, 却牺牲 heat resistant property.

     B- toughening agent 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, and speed expand 展, 导致胶层 cracking, resistant fatigue, therefore can as is structure bonding use.

     C- PBT toughening agent from upper toughened and increase different, toughened it make material overall 柔化, is will ring oxygen resin solid material versus system formed more versus system, toughening agent poly formed pellets in ring oxygen resin crosslinked 网络构 formed versus in formed dispersion versus, resistant cracking property can 发生突变, fracture tough property significantly improve/increase, force property can, heat resistant property loss relatively small.
