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.

CPE separation 子式: CH2-CHCl-CH2-CH2 ]n

英文简称: CPE or CM chlorine polyethylene (PE) (CPE) is saturated and polymer/macromolecule material.

features

due to CPE separation 子不含 di 链, tool has good weather resistance, meanwhile tool has resistant property, heat stabilized property excellent 于PVC, cost low, property can excellent 良. solvent 于芳烃 and 卤代烃, solvent 于脂肪烃, in 170℃ above separation understanding, chlorine hydrogen gas 体, its tool has stability chemical structure, excellent resistant aging property, resistant property, resistant property, weather resistance, color property, chemical resistant product property, resistant oxygen property and electrical insulation property and good versus property and processing property, can and PVC, PE, PS and 橡胶掺 mixed 以改进 its material property.

effect/influence CPE property can large factors:

第一: 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.

第二: 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.

第三: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.
