Chemical & Material Interaction Analysis

Water, Salt is classified as a food, beverage, natural oil & aqueous media (requires FDA/sanitary-grade material stability and resistance to mild organic acids or salts). Used in sanitary food & beverage processing, agricultural storage, and utility water systems. 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.
