Frequently Asked Questions
What is the chemical name and CAS for Polyoxypropylenediamine (Mn ≈ 4000)?
It is poly(oxypropylene)diamine, a long-chain amine-terminated poly(propylene oxide) diamine of average molecular weight near 4000 (CAS family 9046-10-0).
What is Polyoxypropylenediamine (Mn ≈ 4000) used for?
It is a high-molecular-weight soft-segment amine for spray polyurea and flexible polyurethane elastomers. It is also used as a toughening flexibilizer in epoxy systems where high elongation is required.
Why choose the Mn ≈ 4000 grade over shorter polyetheramine grades?
Its very long poly(propylene oxide) chain provides extended, highly flexible soft segments, yielding cured systems with greater elongation and toughness than short grades. This suits elastomeric polyurea and flexible polyurethane builds.
What is the HS code for Polyoxypropylenediamine (Mn ≈ 4000)?
It is classified under HS 3907.20 (other polyethers, in primary forms). Confirm the destination-country tariff line with your customs broker.
How is Polyoxypropylenediamine (Mn ≈ 4000) supplied in bulk and quoted?
It is supplied as a bulk amine liquid in drums, totes, and IBCs. Request a bulk quote with your target quantity for current pricing, lead time, and CoA/SDS.
What is the REACH and TSCA regulatory status of Polyoxypropylenediamine (Mn ≈ 4000)?
Polyoxypropylenediamine (Mn ≈ 4000, CAS 9046-10-0) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 618-561-0).
