Chemical & Material Interaction Analysis
Acetic Acid, Glacial is classified as an organic / weak mineral acid (mild to moderate acidic hydrolysis and potential elastomer swelling). Used in food processing, pharmaceutical formulation, buffering, and industrial cleaning. When selecting wetted components for Viton, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Causes rapid, catastrophic material failure—including severe dissolution, stress cracking, extreme volumetric blowout (>25% swell), or rapid pitting corrosion (>50 mpy).
- 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.
