AMINES & Polypropylene Compatibility

Amines are organic nitrogen compounds derived from ammonia, including ethanolamines (MEA, DEA, MDEA), ethyleneamines and alkylamines. Most are alkaline, many are corrosive to skin and some are flammable; this entry reflects a heavier amine solution with a specific gravity of about 1.13. Amines are used in gas sweetening (H2S and CO2 removal), corrosion inhibitors, surfactants, epoxy curing agents and pharmaceuticals. Confirm the specific amine before selecting tank materials. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.

At a glance

Polypropylene is the recommended tank material for Amines, rated Good. Avoid nylon tanks; PVC and CPVC fittings; Buna-N and Viton® gaskets. Rated Fair (contact us before use): HDPE tanks and HDPE fittings.

  • Excellent No or minor effect. Recommended.
  • Good Slight effect. Generally suitable.
  • Fair Moderate effect. Limited or conditional use — contact us.
  • Not Recommended Severe effect. Do not use.
  • No Data Not tested. Contact us before use.
