  1. 1. WESTMOONINT (HK) CORPORATION LIMITED1 CSM-40 and CSM-45 Technical Data Sheet 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 3-5mm, 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. Figure 1 shows the basic structure of the polyethylene chain that the chlorine and sulfur atoms modify to form cross-linked CSPE molecules. Figure 1 WestMoonint provides CSM-40 and CSM-45 grades are separately similar with Hypalon-40 and Hyplaon-45, which were trademarked by DuPont.

  4. 4. WESTMOONINT (HK) CORPORATION LIMITED4 Chlorosulfonated-polyethylene is used in a number of applications. Variety of products are made using Chlorosulfonated-polyethylene. Some of the popular uses and applications of Hypalon or chlorosulfonated polyethylene (CSM) are as follows: i. Adhesives ii. Insulation iii. Shoe soles iv. Automotive components like high-temperature timing belts, power steering v. Coatings vi. Flexible tubes vii. Seals viii. Flexible magnetic binders ix. Industrial products such as hose, rolls, seals, gaskets, diaphragms and lining for chemical processing equipment x. Jacketing and insulation for wire and cable xi. Liners and covers for portable water reservoirs xii. Variety of protective and decorative coatings Packaging Chlorosulfonated-polyethylene are stored in polyethylene woven bags, and each of them can contain 25 KG in net weight. Storage Chlorosulfonated-polyethylene does not belong to the inflammable and explosive dangerous goods. CSM should be stored in a cool, dry place. Storage and work areas should be monitored for carbon tetrachloride to assure that the PEL is not exceeded.
