Chemical & Material Interaction Analysis
Isopropyl Alcohol (99%) is classified as an alcohol / glycol / polyol (hydrogen-bonding solvent profile; generally mild on polyolefins and metals). Used in heat-transfer loops, de-icing, solvent formulation, and pharmaceutical processing. When selecting wetted components for PVC, 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 (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.
