| Product Name: | TOSO-CSM
|
| Generic Name: | Chlorosulfonated Polyethylene
|
| Chemical Formula / Diagram: | 
|
| Product Overview: | TOSO-CSM is produced from polyethylene by chlorination and chlorosulphonation with chlorine and sulphur dioxide gas. Various types of TOSO-CSM are obtained according to degree of chlorination and chlorosulphonation as well as sort of polyethylene polymer. TOSO-CSM has excellent resistance against ozone, weather, oil and chemicals. And it can be colored in brilliant shades. TOSO-CSM is used for hoses of automobiles, gas and other industrial use, electric cable, rubber coatings, packings, gasket, rolls and lining, adhesives and bounding systems, etc. For goods of daily use, TOSO-CSM is used for life boats, life-jackets, windbreakers, raincoats, handrails of escalator and municipal gas hoses, etc.
