WELLPREN TM ELASTOMER: Chlorinated Polyethylene (CPE) CM SERIES

Chlorinated polyethylene is a heat, weathering and oil resistant elastomer that has used in many wire/cable, hose, automotive and industrial parts for many years. Its unique combination of heat and oil resistance makes it an ideal choice for many under the hood applications. It is also gaining increasing use in many industrial hoses, replacing some well-established materials such as CR due to concerns over high cost and availability. Since CM provides superior heat aging and excellent ozone resistance, it is increasingly used to replace some traditional materials to upgrade the end products performance.
By using HPDE of different molecular weight and molecular weight distribution, adjusting the production process, many types of WELLPREN TM Chlorinated Polyethylene (CPE) CM elastomers can be produced by Sundow, now 6 types are commercially available in the market in large scale, which have different chlorine contents and Mooney viscosities, applicable for different fields and different processing conditions.
 
Characteristics of WELLPREN TM Chlorinated Polyethylene (CPE) CM
As special synthetic rubber, WELLPRENTM Chlorinated Polyethylene (CPE) CM has superior comprehensive performances and good performance-price ratio. Therefore, lots of customers choose WELLPREN TM CPECM for substitution of CR and CSM.
 
- Excellent chemical, heat, and ignition resistance
- Performance over a broad temperature range
- Outstanding heat-aging characteristics
- Unique crumb form, permitting easy blending, formulating, and processing
- Polymer shelf stability measured in years
- Good processability on equipment common to the rubber industry
- Attractive economics

Application of WELLPREN TM CPE CM
1. Automobile Hoses and Industrial Hoses.
As WELLPREN TM CPE CM has outstanding temperature resistance, oil resistance, chemicals resistance, ozone resistance and weatherability, WELLPREN TM CPE CM has become good materials for automobile industry, including applications in oil tubes, delivery tubes for cooling fluid, power steering tubes and outer layers of many other rubber hoses. WELLPREN TM CPE CM is also used for automobile vacuum tubes and vent tubes. Hoses for oil delivery and chemical delivery in industries are another quickly increasing market.
 
 
2. Wires and Cables.
WELLPREN TM CPE CM is widely used in fields of wires and cables, including isolation layers of various types of oil resistant parallel flexible wires (such as HPN cords), sheath for flexible wires or flexible cables for electrical appliances (like electric heater, cooking utensils, air conditioners and refrigerators), sheath for various types of light, middle-weight and heavy cables, sheath for mining cables, marine cables and locomotive cables, isolation layer or sheath for various types of power cables, instrument cables and control cables. Due to WELLPREN TM CPE CM’s superior performance-price ratio and its vulcanized compound’s long time storage at room temperature, it has become the first choice for customers for substitution of CR.

 
3. Various Types of Specialized Rubber Products.
Due to WELLPREN TM CPE CM’s superior heat resistance, oil resistance, chemicals resistance and aging resistance, it can be used for production of special rubber products like sealing rings, pads and liners. 
 
 
4. Combined use of WELLPREN TM CPE CM with other rubbers.
Like EPDM, NBR and BR will not only reduce production cost, but compensate performance deficiencies of other compounds.
 
 
5. Application in Magnetic Materials.
WELLPREN TM CPE CM has very high filling capacity for ferrite magnetic powders. Magnetic rubber products produced from WELLPREN TM CPE CM has superior low temperature performances and is widely used in application like refrigerator sealing strips and magnetic cards. Magnetic components used in electromechanical products can also be made from WELLPREN TM CPE CM by using its thermal resistance. (Refrigerator sealing strip; Magnetic rubber rings in computers and micro motors).
