General Introduction
ASTM D-2000 Classification: CE
Chemical Definition: Chlorosulfonated-Polyethylene
Abbreviation: CSM, CSP, CSPE
Formula: {[(CH2) n1CHCl (CH2) n2] n3cCHSO2Cl} n
Chlorosulfonated-Polyethylene Properties
Chlorosulfonated-Polyethylene (CSM) is a 3-5cm, white to light yellow or yellow-brown tasteless chips, which is similar to rubber but has its own features. It dissolves in aromatic hydrocarbons and chlorine, insoluble in ketones, lipids, and cyclic hydrocarbons, water, alcohol and mineral oil, vegetable oil etc.
Chlorosulfonated-Polyethylene (CSM) is non-toxic, in explosive. It offers excellent properties of ozone resistance, weather ageing resistance, chemical resistance, good physical and mechanical performance, heat ageing resistance and low temperature performance, oil resistance, resistance to flammability, abrasion resistance and electrical insulation, etc.
WestMoonint provides CSM-40 is similar with Hyplaon-40, which was trademarked by DuPont.
