Chemical & Material Interaction Analysis
Hydrogen Peroxide (35%) is classified as a halogen / strong oxidizing agent (free-radical oxidation, polymer chain scission, and severe halide pitting in stainless steels). Used in water disinfection, bleaching, pulp & paper processing, and chemical oxidation. When selecting wetted components for EPDM, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Causes slight surface absorption, minor weight gain (1%–5% swell in polymers), or a low corrosion rate (<2 to 20 mpy in metals) up to 120°F (49°C).
- 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.
