Descripción del producto

CPE resin is one kind of rubber high molecular material made of high-density polythene resin after chlorination reaction. From the molecular constitution, we can see that CPE can be seen as random copolymer of ethane, chloroethylene and 1, 2 acetylene dichloride; its molecular chain is saturated and the polar chlorine atoms are in random distribution, thus, it has the good mechanical and chemical properties and is widely used in machinery, electric, chemical, mine and building material industries. The heat resistance, resistance to ozone and weather and aging resistance of CPE are better than those of rubber; its oil resistance is better than that of NBR and CR; its aging resistance is better than that of CSM and it can resist the corrosion medium of acid, caustic and salt etc. It's innocuity, flame resisting and no explosion hazard.
CPE product can be classified into two categories: general type and rubber type. The former is used for plastics modification, and the latter is used for making elastomer material.
