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