WELLPREN®ELASTOMER: 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®CM elastomers can be produced by Sundow, these 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®CM

As special synthetic rubber, WELLPREN®CM has superior comprehensive performances and good performance-price ratio. Therefore, lots of customers choose WELLPREN®CM 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
