top grade N-Methyl pyrrolidone                                               

 USE

As a high-selective solvent, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and easy to recovery. It is mainly used in the electronic industry in the following aspects:(1) As solvent of poly(1,1-difluoro-Ethene); or electrode's accessory material of lithium ion battery.

(2)As remover liquid of photoresist; in the production of LCD materials; (3)As solvent in pharmacy; (4)Cleaning of precision instruments and circuit board
