Chemical & Material Interaction Analysis
Turpentine 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 EPDM, 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 (EPDM): Outstanding resistance to polar fluids including ketones (acetone, MEK), alcohols, glycols, phosphate ester hydraulic fluids (Skydrol), alkalis, and dilute acids. However, exhibits rapid, catastrophic volumetric swelling and softening when exposed to petroleum oils, gasoline, diesel, kerosene, aliphatic/aromatic hydrocarbons, and chlorinated solvents.
- Application Scope: Common wetted components include butterfly valve liners, O-rings, sanitary Tri-Clamp gaskets, caustic dosing hoses, and water/wastewater treatment seals.
