A Polar Aprotic Medium for Demanding Polymer Systems
Dimethylmethanamide, commonly known as DMF, is a polar aprotic solvent that mixes with water and many organic solvents. Wenzhou Yu'ao Electric Co., Ltd. supplies this grade with a reference purity of ≥99.9%. It is used to dissolve polyurethane resins and prepare synthetic leather slurries. Its solvent strength and concentration affect solution behavior and can influence the properties of chemical fibers and coatings.
Formulation Adjustments
In synthetic leather production, DMF is commonly used to prepare slurries for wet-process applications. Polyurethane processors use it as a solvent for resin systems, with the required ratio depending on the formulation and processing conditions. It is also used as a polar solvent in chemical synthesis when the solubility of the target material is a key consideration.
Compatibility and Purchasing
Before placing a bulk order, buyers should check the solvent's compatibility with their resin systems. For applications with specific limits on water content, acidity, or color, these requirements should be provided during the inquiry so the available specification can be evaluated. OEM and ODM supply options are available, with labeling and packaging details agreed upon before the order is finalized. Paid samples can be arranged for initial process trials, subject to quantity confirmation. The regular minimum order quantity is 15 tons.
Packaging and Order Fulfillment
Dimethylmethanamide is available in 190 kg drums, IBC totes, or bulk tank cars, depending on the order requirements. Production includes in-process checks and a final inspection before packaging. Third-party inspection can also be arranged, with sampling methods and acceptance criteria agreed upon when the order is confirmed. Export-compliant drums are available. Payment is made in full in advance in RMB or USD. Delivery schedules depend on stock availability and order details. Available trade terms include EXW, FOB, and DDP.
FAQ
