CSM (chlorosulfonated polyethylene) is a specialty elastomer widely considered where long-term weather, ozone, UV and chemical resistance are required. It is commonly used in hose covers, cable jacketing, coated fabrics, protective linings and exposed industrial rubber parts.
Material overview
CSM Rubber is a chlorosulfonated polyethylene elastomer family valued for its combination of weatherability, ozone resistance, chemical durability, flame-conscious compounding potential and adhesion versatility. YQXPOLYMER positions this material within a focused specialty-elastomer portfolio and supports customers with grade selection, technical documentation, sample evaluation and application-oriented discussions.
Why engineers consider CSM Rubber
Weather & ozone resistance
A saturated backbone helps CSM maintain performance in long-term outdoor exposure.
Chemical durability
CSM is often selected for acids, alkalis, oxidizing environments and industrial chemical exposure, subject to concentration and temperature.
Processing versatility
Grades can be selected for rubber compounding, extrusion, calendering, coating and related processing routes.
Typical application areas
- Industrial and automotive hose covers
- Wire and cable jacketing
- Rubber-coated fabrics
- Chemical-resistant linings and sheets
- Marine and outdoor rubber components
- Seals, gaskets and molded industrial parts

Frequently asked questions
CSM is the generic polymer family. Hypalon® was a DuPont trademark for certain CSM products and should not be used as a generic brand name for current YQXPOLYMER material.
No. CSM can be advantageous where chemical, weather, ozone and flame-conscious performance must be balanced, but EPDM, CR, NBR, FKM and other elastomers may be more appropriate in other environments.
No. Processing behavior and final performance vary by grade and formulation. Select the grade around the component and compound design.
