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 PTFE, 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 (PTFE): Near-universal chemical inertness across strong mineral acids, concentrated caustics, ketones, esters, chlorinated solvents, and amines up to 500°F. However, susceptible to cold flow (creep) under high mechanical load and reactive only with elemental fluorine gas, chlorine trifluoride, or molten alkali metals.
- Application Scope: Common wetted components include lined chemical transfer piping, diaphragm pump elastomers, ball valve seats, expansion joints, and high-purity semiconductor fluid handling.
