     PC toughening agent and other plastics toughening agent is can versus 容 吗? versus very more 人也跟我 has issues, that 么PC toughening agent remove can and other toughening agent versus outer, it true positive use value has which 呢?

    

      1, PC toughening agent is currently development toughening agent main/primary day is is improvement hard polyvinyl chloride (PVC) property. world upper hard polyvinyl chloride (PVC) use amount growth and toughening agent, processing modifier day development has 密切 关系. USA is 例, 1965 year polyvinyl chloride (PVC) in hard 质 占10%, 1970 year rise is 20%, to 1975 year 占40%, 1980 year ultra- 50%, expected to 2000 year will 达75%. add increase agent polyvinyl chloride (PVC) in 40℃ below/following 时就呈脆 property, but also in add relatively less increase agent 时, not only can toughened 反而促 make its property, this is 谓 反 increase 塑效应, therefore add toughening agent hard polyvinyl chloride (PVC) has very large use value. toughened polyvinyl chloride (PVC) method is through copolymer let polyvinyl chloride (PVC) inner increase 塑, method not only but also 效果不佳. 不久发现添 add certain elastomer can reduce polyvinyl chloride (PVC) temperature degree, most commonly used additives is 二烯烃 or acrylic polymer, especially is butadiene polymer due to its 玻璃化 temperature degree low tool has most good toughened property, 例如ABS, MBS is polyvinyl chloride (PVC) most commonly used main/primary toughening agent. in addition, 0PE and EVAJ, type 橡胶, acrylic ester polymer and surface use hard acid coating carbon acid and other is polyvinyl chloride (PVC) has toughening agent.

 

      2, PC toughening agent understanding to PBT modified in use compatibilizer and toughening agent. JB-A09 is PBT specialized versus toughening agent, generally in PBT reinforcement or anti modified in use 5-10% JB-A09就 can to very good toughened 效果. another company can compatibilizer JB-A08 and JB-A01（ front already 述） in PBT modified in tool has very good versus toughened property. 当然, generally compatibilizer due to is elastomer is 载体, use amount more for anti property has effect/influence, therefore use in use 时应考虑 in improve/increase impact strong/high degree and decrease/reduce anti property effect/influence 方面寻找一 combined balanced, generally 说, compatibilizer use amount in 8% below/following, for PBT anti property effect/influence is large.
