The CSM molecule contains chlorine and sulfonyl chloride (-SO2Cl). It is obtained by treating a boiling solution of polyethylene and carbon tetrachloride with gaseous chlorine and sulfur dioxide. A polymer with 29% to 43% chlorine and 1% to 1.5% sulfur is thus produced. The properties of the various types of CSM mainly depend on:
In general, they perform well under a fairly wide range of temperatures (-40, +135°C). They exhibit good weathering and ozone resistance.
These polymers show low permeability to steam and gases.
They are compatible with silicone oils, aliphatic hydrocarbons, organic and inorganic acids. They also have good dielectric properties.
