Chemical & Material Interaction Analysis
Ink is classified as an industrial process chemical (requires verification of concentration and thermal operating envelopes prior to deployment). Used in chemical manufacturing, fluid transfer, and industrial storage systems. When selecting wetted components for HDPE, 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 (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.
