Chemical & Material Interaction Analysis
Acrylonitrile is classified as a polar organic solvent (ketone / ester / ether) (strong solvation power that rapidly swells or dissolves many elastomers and amorphous thermoplastics). Used in industrial degreasing, coatings, resin dissolution, and pharmaceutical extraction. When selecting wetted components for PVDF, 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 (PVDF): Superior mechanical strength and abrasion resistance compared to PTFE, with exceptional resistance to halogens (wet/dry chlorine, bromine), strong acids, and oxidizers. However, attacked by strong polar aprotic solvents (acetone, MEK, DMF, DMSO, NMP), primary amines, and high-concentration caustic soda (NaOH >50%) which cause dehydrofluorination.
- Application Scope: Common wetted components include high-purity acid distribution lines, wet-bench chemical etching systems, bleach/halogen injection quills, and magnetic-drive pump heads.
