Quick AnswerUse this table to shortlist a YQXPOLYMER CSM grade by chlorine level, Mooney/process window and application. Web data is a screening reference; the current controlled TDS and customer validation govern purchasing and qualification.

* CSM-301H / CSM-301L values are shown as 25% toluene solution viscosity at 25°C in the currently published YQXPOLYMER product data. Confirm the latest TDS before specification.
How to select a grade
- Define the component and processing route first.
- Confirm the chemical, oil, fuel, weather or ozone exposure.
- Confirm continuous and peak temperature.
- Set target hardness, tensile, elongation, compression and flex requirements.
- Compare mixing, extrusion/calendering and cure response against the incumbent grade.
- Qualify the final compound, not the base polymer alone.
Trademark / equivalency note: Historical Hypalon® references can help engineers understand legacy specifications, but YQXPOLYMER does not treat a grade name as proof of drop-in equivalence. Cross-supplier replacement requires side-by-side validation.
