Chemical & Material Interaction Analysis
Furfural 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 HDPE, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Causes rapid, catastrophic material failure—including severe dissolution, stress cracking, extreme volumetric blowout (>25% swell), or rapid pitting corrosion (>50 mpy).
- Material Profile (HDPE): High impact strength (even at sub-zero temperatures) and excellent resistance to mineral acids, caustics, salt brines, and alcohols. However, lower upper temperature limit (140°F/60°C) than Polypropylene, with susceptibility to permeation and environmental stress cracking in aromatic/chlorinated hydrocarbons and strong oxidizers.
- Application Scope: Common wetted components include bulk chemical storage tanks, IBC totes, double-containment underground piping, and chemical drum liners.
