A: DMAC has a higher boiling point (165 °C vs. 153 °C for DMF) and better thermal/hydrolytic stability. It also tends to absorb less moisture and is often preferred for hightemperature polyimide processing. However, DMF is cheaper and more widely used in general reactions. DMAC is the standard for spandex and polyimide applications.

A: Yes, DMAC is completely miscible with water in all proportions. It is also miscible with most organic solvents (alcohols, ethers, ketones, aromatics, chlorinated solvents).

A: DMAC is a teratogenic hazard – avoid skin contact and inhalation. Use closed systems and wear chemicalresistant gloves (butyl rubber or PVA), goggles, and a respirator if ventilation is poor. DMAC is also a flammable liquid (flash point 70 °C). We provide a detailed MSDS with every shipment.

A: 24 months when stored in original sealed containers in a cool, dry, wellventilated area, away from strong oxidizers and light. After opening, store under nitrogen to prevent moisture pickup, which can lead to acetic acid formation.

A: We offer 190 kg net steel drums, 1000 L IBC totes (approx. 940 kg net), and bulk ISO tank containers (up to 20 tons). All packaging meets UN hazardous goods regulations (UN 3314, Class 3, PG III).

A: One drum (190 kg) for trial evaluation. Commercial orders start from 2 tons (approx. 10 drums or one IBC tote). Bulk tank orders (15–20 tons) are available with significant price advantages.

A: Commercial invoice, packing list, Bill of Lading, COA, MSDS, DG declaration, and upon request: Certificate of Origin (C/O), GHS labels, REACH compliance letter, or phytosanitary certificate (if required).
