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 PVC, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Exhibits minor chemical interaction—such as slight discoloration, mild dimensional swell, or slow uniform surface etching—that does not immediately compromise structural integrity.
- Material Profile (PVC): Cost-effective, rigid corrosion resistance against mineral acids, alkalis, sodium hypochlorite bleach, and inorganic salt brines at ambient temperatures. However, low upper temperature limit (140°F/60°C) and immediate solvation/softening upon contact with ketones, esters, ethers, aromatic hydrocarbons, and chlorinated solvents.
- Application Scope: Common wetted components include Schedule 40/80 chemical feed piping, water/wastewater treatment headers, acid scrubbers, and ball/diaphragm valves.
