Quick Answer
Chemical-service elastomer selection must be based on exact chemical identity, concentration, temperature and immersion time.
Engineering requirements
- Chemical identity
- Concentration
- Temperature
- Continuous vs intermittent contact
- Mechanical load
- Cleaning/sterilization chemicals
Recommended material families
| Material | Role / reason |
|---|---|
| CSM | Primary platform for weatherable chemical-resistant rubber parts, linings, sheets and hose covers. |
| ECO / GECO | Useful for selected oils, fuels and industrial fluids where permeability/sealing are important. |
Why material selection matters
CSM has broad chemical resistance, but no elastomer is universally resistant. Use compatibility charts only as a screening step.
What to confirm before selecting a grade
- No. It is an engineering screening reference and should be confirmed by immersion testing under representative conditions.
- Chemical name/CAS if possible, concentration, temperature, exposure duration, component type and incumbent material.
Application note: The final elastomer and compound must be validated in the actual medium, temperature, pressure, dynamic condition and regulatory environment. Published generic resistance rankings are screening tools, not a substitute for application testing.
