N-Methyl Pyrrolidone(NMP) is a very important chemical intermediate which is widely used in many fields such as:
(1) Recovery of Pure Hydrocarbons in Petrochemical Processing;
(2) Desulfurization of Gases;
(3) Plastics;
(4) Sufrace Coatings;
(5) Paint Stripping and Cleaning;
(6) Plant Protection;
and (7) Electronic Equipment Manufacture etc.
Now China's GBL capacity has reached 80-90ktpa, Lejoin, as a reliable BDO supplier for several decades, has extened its BDO strength into high effective solvent like GBL/NMP from 2008, we have signed strategic cooperation agreement with China's GBL/NMP manufacturer, and our cooperation is based OEM business model. We can control our production cost and promise product quality.
We have successfully exported our products to many contries like Korea, Taiwan, Japan, Russia, USA, Belgium etc. and our product has been highly recognized by our customers.
