what is PC toughening agent ? PC toughening agent application in 哪里?
    
toughening agent has very multiple, for different product has versus for toughening agent, comparison more toughening agent ratio 如说: PS toughening agent generally add amount is 5-10% left right, PP toughening agent generally add amount is 5% left right, PBT toughening agent generally is 3% left right, PC toughening agent generally is 10%-20% left right to relatively 佳效果, PVC toughening agent generally add amount is 10% left right, PE toughening agent generally is 5%-30% between, use is types toughening agent 呢?     

PC toughening agent is types 核―― housing/shell structure toughening agent, is butadiene （Ｔg∠-68℃）橡胶, outer housing/shell is polymethyl methacrylate (PMMA).

PC toughening agent advantages:   

1. normal temperature toughened 效果均 very excellent, make in －40~－50℃ lower, can make by toughened material maintain tough property: for its it force property can effect/influence very small, comprehensive property can excellent. in ＰＣ in, add 入3%就 has toughened 效果.   

2. in polyester in dispersion very good, and for by toughened material flow property effect/influence very small （ its it grafting type or copolymer type polyester toughened, make by modified polyester flow property very 差, easy injection ）, effect/influence injection. in injection process in, PC toughening agent toughened for polyester for 剪切不敏感, has injection conditions selection.   

3. toughened polyester, color can force 极佳, can decrease/reduce color powder add amount.  

4. toughened ＰＣ, resistant force cracking property good, meanwhile improvement for water property.     

5. in use grafting type or copolymer type toughening agent toughened polyester processing 结束後, is anti screw inner crosslinked, upper machine; use 特炫PC toughening agent toughened polyester processing 时, use crosslinked 发生.
