CSM grades typically contain 20 to 45 percent chlorine, providing good ozone, UV, weathering, and chemical resistance. Oxidizing substances, hot water (when cured), and corrosive compounds are all examples of this. It also has high electrical qualities, as well as good resistance to dry heat up to 150°C, low flammability, and low gas permeability. However, depending on the chlorine content of the CSM grade, it has poor/fair fuel resistance and its low temperature properties are often limited. Furthermore, it has a low compression set.
Fast cross-linking (vulcanization) with substances such multifunctional amines and peroxides is a major advantage of CSM rubber. At the sulfonyl groups, it can also be crosslinked with sulfur and thiuram accelerators. However, when compared to peroxide cured rubber, this type of vulcanization is slower and the physical qualities are typically worse.
The weatherability, UV stability, and adhesion capabilities of CSPE have made it particularly popular as a commercial roofing material. Sheathing for wire and cable, as well as paint, are some of the other applications. Tubes, tank linings, acid-resistant and ozone-resistant protective layers, as well as rubber gaskets and other goods, are among the additional applications. Shoe soles and garden hoses are two well-known consumer items.
