Shanghai Daoqin Plastics Co., Ltd.

随 plastics industrial development,ABS toughening agent in 交通, aviation, electrical appliances, day use furniture and other field/area in already to application,但现 in for material day fine requirements make used for different application areas ABS toughening agent need tool has different property can.

 

    toughening agent use amount increase,材 material impact strong/high degree has increase, in toughening agent use amount stage/phase and for different types type toughening agent, impact strong/high degree increase degree same. types toughening agent in quality separation is 0～2% scope/range inner for material toughened function comparison obvious,当 quality separation ultra- 出2%以 rear, impact strong/high degree basic property upper rise trend,TPU toughened most 佳; its is PW2151 and SBS, toughened 效果以CPE most 差. toughening agent quality separation ultra- 7%时,ABS grafting powder material PW2151 for material toughened obvious excellent other types toughening agent,材 material impact strong/high degree improve/increase degree increase large trend.

 

    use different toughening agent toughened 0215A obtain material extrusion increase, impact strong/high degree has decline,但 is different material for 剪切 敏感程 degree different, performance is TPU toughened material degradation degree most small, this is is 首先TPU本身 di formed separation less, but also TPU本身 tool has good processing properties, for 剪切 敏感程 degree low, therefore extrusion increase,材 material impact strong/high degree decline degree most low; use ABS grafting powder material toughened material impact strong/high degree decline degree most large, this is is PP toughening agent powder material in di formed separation more,本身 heat stabilized property good,容 easy degradation, but also powder material flow property 差, for relatively is 敏感, therefore extrusion increase its impact strong/high degree decline degree most large;而 use SBS toughened material 介于两者 between, is is although SBS heat stabilized property relatively good,但 is its flow property has TPU good, for 剪切 敏感程 degree and di content relatively TPU more, therefore performance is relatively TPU toughened material stability property 稍差; but also is types material in has ABS grafting powder material formed separation, therefore can 判断出 in use TPU and SBS toughened material impact strong/high degree decline main/primary is is its in powder material formed separation degradation 致.
