Chemical & Material Interaction Analysis
Vinyl Chloride is classified as a halogenated hydrocarbon / refrigerant (high diffusivity and strong non-polar solvent swelling in polyolefins and standard rubbers). Used in vapor degreasing, refrigerant loops, chemical extraction, and polymer manufacturing. When selecting wetted components for Viton, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Exhibits negligible weight change, zero surface crazing, and minimal dimensional swelling (<1%) across extended immersion testing.
- 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.
