YQXPolymer Specialty Elastomers

YQXPOLYMER

CO Rubber

CO Rubber by YQXPOLYMER for specialty fuel, oil, permeability and sealing applications.

Quick Answer

CO Rubber is a Epichlorohydrin homopolymer selected for very low permeability and strong fuel/oil barrier positioning. Final performance depends on the exact grade, compound formulation and cure system.

Material overview

CO Rubber is Epichlorohydrin homopolymer with very low permeability and strong fuel/oil barrier positioning. 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 CO Rubber

Barrier performance

CO is commonly screened where low gas/fuel-vapor transmission is a primary requirement.

Fuel and oil resistance

The polymer family is used in fluid-contact components requiring hydrocarbon resistance.

Ozone resistance

Saturated backbone characteristics support ozone-aging resistance.

Typical application areas

  • Fuel-vapor hose layers
  • Barrier components
  • Fuel-system seals
  • Specialty industrial seals
Selection principle: Fuel-vapor hose layers is a typical screening direction. Final selection must compare the exact service fluid, temperature and mechanical duty. Final grade selection should be confirmed against the customer’s medium, temperature, processing method, cure system and target physical properties.

Frequently asked questions

No. Generic charts are useful for screening, but the final compound must be tested in the actual fluid and temperature range.

No. Supplier nomenclature and exact polymer composition can differ. Compare controlled technical data rather than relying on the family name alone.

Yes. Share the component, fluid, temperature, processing method, current material and target properties.
