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

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.
