    Properties:

    Colorless transparent liquid, it has strong water absorption. It can almost dissolve in all the solvents

    Uses:

    As a high-selective polar solvent and nitrogen heterocycle compound, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and high selectivity.

    N-Methyl-pyrrolidone (electronic grade) is mainly used in such fields as:
    (1) As solvent of poly (1, 1-difluoro-Ethene); or electrode's accessory material of lithium ion battery.
    (2)As remover liquid of photo resist in the production of LCD materials;
    (3) As solvent in pharmacy;
    (4) Cleaning of precision instruments and circuit board.
