Chemical & Material Interaction Analysis
Trichloropropane 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 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.
