BUTYL AMINE & Polypropylene Compatibility

Butyl Amine (n-butylamine, C4H9NH2, CAS 109-73-9) is a colorless, highly flammable liquid with a strong ammonia-like odor, a specific gravity of about 0.74, a boiling point near 172°F (78°C) and a flash point near 10°F (-12°C). It is corrosive to skin and eyes. Butylamine is used to make rubber vulcanization accelerators, pesticides, pharmaceuticals, dyes and emulsifiers. Store in grounded, vented tanks away from acids and oxidizers. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.

Not recommended in PVDF. Arkema, the maker of Kynar®, does not recommend Kynar Flex® 2850 PVDF, the resin we mold, for long-term service with Butylamine (Aqueous solution or liquid). Ask us about HDPE or polypropylene for this chemical. Arkema’s limits are for solid resin at atmospheric pressure and do not account for mixtures.
