        CPE即 chlorine polyethylene (PE), specialized high density polyethylene (PE) (HDPE)经 chlorine made, use chlorine 原子部 separation 取代HDPE separation upper hydrogen 原子 产 material. drying rear is white powder 末, 无毒.

         effect/influence CPE property can large factors:

        1, use PE types type

        由 polymer/macromolecule amount polyethylene (PE) CPE has relatively high degree and tensile strength, this type of CPE and PVC resin 间 附 force low, use low molecular weight polyethylene (PE) CPE degree and tensile strength relatively low, using/adopting high density polyethylene (PE) CPE has good heat resistant property can.

        2, raw materials pellets large small

        粒 degree small easy formed or block 状CPE, large chlorine distribution non-uniform, difficult solvent has machine solvent agent, degree scope/range in 0.1-200 μm most 佳.

        3, CPE chlorine degree high low

         chlorine content in 25% below/following 时, and PVC versus property 差, can as is modifier use; chlorine content large 于40%时 and PVC versus property good, can as is solid increase agent use, combined impact modifier; chlorine content is 36-38% CPE tool has good elastic property and and PVC versus property, 因而广泛 used as PVC impact resistant modifier.

        现 use most more is chlorine 35% CPE, chlorine content in 35% left right CPE its crystallization degree and 玻璃化 temperature degree relatively low, tool has good elastic property, and and PVC has versus property, by as PVC hard products impact resistant modifier function.
