N - Methyl - 2 - Pyrrolidone (NMP)

1 of 2 products in this brand
N - Methyl - 2 - Pyrrolidone (NMP) is a solvent in the pyrrolidones family. Recognized for its high solvency, low freezing point, and hygroscopic properties, NMP serves diverse applications. With a low freezing point, high boiling point, and high flash point, it excels in industrial additives, particularly in lithium-ion batteries for the electrical and electronics market. Packaged in drums, tanks. Our NMP is ensured with high purity by integrated production process from butane - based maleic anhydride.

Features & Benefits

Product Highlights

NMP is a 5-member-ring compound containing nitrogen.  It has a wide range of uses due to the following excellent characteristics.

  • It is highly polar and miscible with most organic solvents (alcohols, ethers, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, etc.).  
  • Organic and inorganic substances are highly soluble in it.
  • It mixes with water in all proportions. It has a high flash point compared to similar solvents.
  • The boiling point is high, the freezing point is low, and handling is easy. It is chemically and thermally stable, and not corrosive.

Applications & Uses

Industrial Additives End Use
Product Applications
  • NMP is used to produce fine chemicals from mass-produced chemicals.
  • NMP applications in the electronics field have expanded in recent years.  NMP's high polarity and high solvency power along with our high purity, high-grade production technology enable the high performance needed in this field.
  • NMP can dissolve organic and inorganic compounds equally well or better than chlorofluorocarbon solvents.  
  • Therefore NMP is used in various industrial fields as a cleaning or release agent.
  • NMP is replacing 1,1,1-trichloroethane in metal cleaning applications due to the world-wide environmental pollution problems associated with chlorinated solvents

Storage & Handling

Storage and Handling Conditions
  • Since NMP is hygroscopic, if moisture content is to be controlled, it is important to keep storage containers tightly closed or under a dry nitrogen atmosphere.  
  • Since NMP is a strong degreaser, in the event of skin contact wash immediately with water.
