Chemical & Material Interaction Analysis
Alcohols: Ethyl is classified as an alcohol / glycol / polyol (hydrogen-bonding solvent profile; generally mild on polyolefins and metals). Used in heat-transfer loops, de-icing, solvent formulation, and pharmaceutical processing. When selecting wetted components for EPDM, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Chemically inert interface with no measurable corrosion, polymer chain scission, or elastomeric swell under standard operating conditions.
- Material Profile (EPDM): Outstanding resistance to polar fluids including ketones (acetone, MEK), alcohols, glycols, phosphate ester hydraulic fluids (Skydrol), alkalis, and dilute acids. However, exhibits rapid, catastrophic volumetric swelling and softening when exposed to petroleum oils, gasoline, diesel, kerosene, aliphatic/aromatic hydrocarbons, and chlorinated solvents.
- Application Scope: Common wetted components include butterfly valve liners, O-rings, sanitary Tri-Clamp gaskets, caustic dosing hoses, and water/wastewater treatment seals.
