  Uses:

  
  Electronic grade NMP:
  (1) is widely used as kynar solvent , as well as the Electrode auxiliary material of lithium ion battery;
  (2) used in photoresist stripper, for the production of LCD liquid crystal material;
  (3) a solvent for pharmaceutical production;
  (4) for the semiconductor industry, precision instruments, PCB Wash.
  Industrial grade NMP:
  (1) used as the organic raw material for the extraction recovery of petrochemical industry. Can be used as the solvent that is recovered from natural gas or pyrolysis gas acetylene from light naphtha, recycling concentration of acetylene is 99.7%; as the extraction agent for the separation and recovery of high pure butadiene from C4 hydrocarbons, the recovery rate is 97 %, purity of recovered butadiene is 99.7%; as the extraction agent for the separation and recovery of high pure isoprene from C5 hydrocarbon, the purity of recovered isoprene is up to 99%; used as the aromatics extraction agent, because of having a high solubility and low vapor pressure to aromatic hydrocarbons, it can offer low loss in the extractant process, and high aromatics recovery.
  (2) for the refining of lubricating oil . It can remover aromatics from lubricants in extraction method.
  (3) used as the solvent of polymer and the polymerization. such as a polymerization solvent for the production of polyphenylene sulfide and aramid, polyimide, polyamide, polyurethane polymer ;
  (4) Since NMP owns a large solubility in the resin, it can be used as the process solvent of resin process, including coatings, floor paint, varnish, composite paint film, IC insulating materials, fiber fabrics and adhesives, etc.
  (5) used in industrial detergent for the cleaning of chemical equipment, clog, attachments, and the coating layer.
  (6) used in pesticides, ink, production aids of pigment and dispersants
