Chemical & Material Interaction Analysis
Aromatic Hydrocarbons is classified as an aromatic hydrocarbon / terpene / phenolic (severe aromatic ring solvation and permeation in polyolefins and non-fluorinated elastomers). Used in petrochemical refining, solvent blending, paint thinners, and chemical intermediates. 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.
