Chemical & Material Interaction Analysis
Sodium Peroxide 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 Viton, 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 (Viton): Exceptional resistance to aliphatic and aromatic hydrocarbons, petroleum oils, concentrated mineral acids, and halogenated solvents at elevated temperatures. However, severely attacked by polar oxygenated solvents (acetone, MEK, ethyl acetate, THF), anhydrous ammonia, primary amines, and hot concentrated caustic soda via dehydrofluorination.
- Application Scope: Common wetted components include O-ring static/dynamic seals, pump diaphragms, valve seats, flange gaskets, and chemical transfer hose liners.
