WebChlorosulphonated Polyethylene Rubber (CSM), also known by its brand name Hypalon®, provides excellent resistance to ozone, oil and many chemicals. This polymer exhibits excellent temperature flexibility with a range of -40 to 250 F. CSM rubber has low gas permeability and provides good resistance to water swell. WebGas permeability falls as the acrylonitrile content increases, and compression set deteriorates. As with most synthetic rubbers, good strength values can only be achieved in acrylonitrile-butadiene rubber by adding active fillers, such as carbon blacks. In addition, the following properties are characteristic of NBR:

In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter.
