Main uses:
Used as a highly efficient solvent for polymerization reactions
NMP has a large solubility to the resin, and its solubility parameters are shown in the following table:
Resin name Solubility % Resin name Solubility Acrylonitrile/polyvinyl chloride polyurethane rubber polyvinyl chloride polycarbonate polyester film
>10 Polyamide >10
10 polymethyl methacrylate >10
>10PVP>10
10 ethyl cellulose 25
>10 acrylonitrile 24
Note: Solubility is the weight of the resin dissolved in 100g of solvent (g).
The solubility parameter of NMP for most resins is about 11, because the solubility is very similar, so the compatibility is very good.
Other applications:
Acetylene concentration and butadiene, isoprene, aromatics extraction
Lubricating oil refining
Polymeric solvent for insoluble engineering plastics (polyphenylene sulfide, polyimide) and aramid fibers
Electronic insulation materials, lithium-ion batteries
High-grade paint, ink, pigment
Pesticide additive
Cleaning agent: deoiling, dewaxing, polishing, rust prevention, paint removal, etc
Artificial kidney functional membrane liquid, seawater desalination membrane liquid
Packing and Precautions:
Supply form 200KG drums. The product has strong hygroscopicity, and the NMP solution that dissolves pesticides has strong permeability to the skin, which should be paid attention to when used.
