Request SDS →Polyetheramine D-4000 (poly(oxypropylene)diamine, CAS family 9046-10-0) is a high-molecular-weight difunctional polyetheramine, a long-chain amine-terminated poly(propylene oxide) diamine of average molecular weight near 4000. It is used as a soft-segment amine for spray polyurea and flexible polyurethane elastomers and as a toughening flexibilizer in epoxy systems. Supplied as a bulk amine.
Frequently Asked Questions
Is Polyetheramine D-4000 an equivalent to Jeffamine D-4000?
Polyetheramine D-4000 is the generic amine-terminated polyether (polyetheramine) commonly sold as Jeffamine D-4000. RawSource supplies an independent equivalent — verified to your specification and Certificate of Analysis — and is not affiliated with, authorized by, or endorsed by Huntsman.
What is the chemical name and CAS for Polyetheramine D-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). The 'D' denotes a diamine and 4000 the approximate average molecular weight.
What is Polyetheramine D-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 D-4000 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 like D-230 or D-400. This suits elastomeric polyurea and flexible polyurethane builds.
What is the HS code for Polyetheramine D-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 Polyetheramine D-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.
