Dissolves difficult polymers
Polyacrylonitrile, spandex polymers, polyimide precursors, PVDF and polysulfones go into solution for spinning, casting and coating.
DMAC
N,N-ジメチルアセトアミド (DMAC) Supplier from China
N,N-ジメチルアセトアミド (DMAC) is a high-boiling polar aprotic solvent used to spin acrylic and spandex fibers, cast polyimide films and PVDF membranes, and as a reaction solvent in pharmaceutical and agrochemical synthesis. SUNCHEM supplies DMAC in drums or ISO tanks with a batch COA on every shipment.

製品概要 & 主な利点
DMAC dissolves polymers that few other solvents can — polyacrylonitrile, polyurethane-urea, polyimide precursors, PVDF and polysulfones — and it is stable to strong bases, which makes it a reaction solvent for pharmaceuticals such as antibiotics and for agrochemicals. Its main volume uses are fiber spinning, film casting, membrane making and wire enamels.
DMAC is classified as toxic for reproduction and is listed as a substance of very high concern in the EU, where its industrial use is restricted to set exposure limits. Tell us your market so we provide the documents you need.
Stable reaction medium
High boiling point and stability to bases suit pharmaceutical and agrochemical reactions.
Specified on your terms
We quote against your purity, water and amine limits and send the batch COA for each lot.

包装 & ストレージ
包装
Drums or ISO tank. Tell us which you need and your unloading set-up.
ストレージ
Keep containers closed in a cool, ventilated store; DMAC is hygroscopic and readily absorbed through skin — follow the SDS for protective equipment.
