Frequently Asked Questions
What is Polyetheramine D-630 used for?
Polyetheramine D-630 is a difunctional polyetheramine of intermediate molecular weight used as a flexibilizing epoxy curing agent that adds toughness to epoxy networks. It also serves as a soft-segment amine in polyurea and polyurethane systems.
What is the chemical name and CAS for Polyetheramine D-630?
It is a poly(oxypropylene)diamine, an amine-terminated poly(propylene oxide) diamine of average molecular weight near 630 (CAS family 9046-10-0). The 'D' denotes a diamine and 630 the approximate average molecular weight.
Where does D-630 sit in the polyetheramine series?
It is an intermediate grade between flexibilizing D-400 and high-MW D-2000, balancing flexibility and reactivity. It is chosen when a system needs more toughness than D-400 provides but shorter segments than D-2000.
What is the HS code for Polyetheramine D-630?
It is classified under HS 3907.20 (other polyethers, in primary forms). Verify the exact tariff line for your destination country with your customs broker.
How is Polyetheramine D-630 supplied in bulk?
It is supplied as a bulk amine liquid in drums, totes, and IBCs. Request a bulk quote with your target volume for current pricing, lead time, and CoA/SDS.
What is the REACH and TSCA regulatory status of Polyetheramine D-630?
Polyetheramine D-630 (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).
