EPDM material notes
Usually a good starting point for
Ozone/weathering, inorganic acids, alkalis, phosphate esters and many polar-fluid services.
Review before use with
Mineral oils and fuels are not default EPDM service; hot-water and steam use remains condition-dependent.
Family-level screening, not an approval of a specific compound. Screen a chemical or ask for a material check.
