Downloads
Controlled TDS/SDS and technical documents should be requested or published only when current.
How to use these resources
- Start with the polymer-family guide when you are comparing material chemistry and general performance.
- Use Material Comparisons when choosing between CSM/ECO and common alternatives such as EPDM, NBR, CR, ACM, HNBR or FKM.
- Use Processing Guides for compounding, cure-system and manufacturing considerations.
- Use Chemical Resistance and Application Engineering resources to define media, temperature, component duty and validation requirements.
- Request the current controlled TDS/SDS whenever a material moves from screening into formal qualification.
