toughening agent 不 is 说橡胶 type toughening agent or is resin type product has more large 差距, good bad its 实并没 has especially 定论, 人们也 more according to need combined selection, is has can can can use types product as.

      a, 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 PC toughening agent 含 butadiene polymer due to its 玻璃化 temperature degree low tool has most good toughened property.

      b, toughening agent suitable for outer use PVC plastics products impact modified, in PVC plastics type use toughening agent as is impact modifier and its it modifier versus ratio tool has processing properties good, surface light 洁, resistant aging good, strong/high degree high features, price ratio CPE high 1／3 left right.

      c, currently development toughening agent main/primary day is is improvement PC toughening agent hard polyvinyl chloride (PVC) property. world upper hard polyvinyl chloride (PVC) use amount growth and toughening agent development, processing modifier day development has 密切 关系.
