Quick Answer
YQXPOLYMER focuses on two specialty elastomer platforms: Chlorosulfonated Polyethylene (CSM) and Epichlorohydrin Rubber (CO, ECO, GECO and PECO).
Material platforms
Chlorosulfonated Polyethylene (CSM)
Weather, ozone, chemical and outdoor-performance elastomer grades.
Epichlorohydrin Rubber
Fuel- and oil-resistant low-permeability elastomers for hose, seals and fluid systems.
How to use this product section
Start from the polymer-family page for chemistry, general performance and grade selection. Use individual grade pages for commercial positioning and request the current TDS for controlled specifications. For component-level decisions, continue to Applications and Material Selection.


From polymer family to validated grade
- Start with the service environment and component function.
- Choose CSM or an epichlorohydrin polymer structure according to the dominant performance requirement.
- Shortlist the commercial grade using viscosity, chemistry, processing and cure requirements.
- Validate the final compound against the actual medium, temperature, dynamic duty and target standard.
