Shandong Qingyun ChangXin Chemical Science-tech Co., Ltd. is a large-scale chemical entity enterprise specializing in manufacturing and operating 1-Methyl-2-pyrrolidinone (NMP) andγ -butyrolactone (GBL) series.
Equipped with the combination unit of 15, 000 T/A of γ -butyrolactone and 15, 000 T/A of 1-Methyl-2-pyrrolidinone, we now are the biggest and most leading hi-tech manufacturer of GBL and NMP in China, with the lowest cost and best quality; We are the up-rising star in this trade. Phase II expansion project will be completed in June, 2011, and then we will have the combination unit of 30000 T/A of γ -butyrolactone and 30000 T/A of 1-Methyl-2-pyrrolidinone. Now, our products are widely used in the production of PCB printed circuit board and TFT-LCD liquid crystal material, the cleaning of IC semiconductor, or used as top-grade and environment-friendly solvent in lithium ion battery industry, electronic insulating materials, top-grade coating, drug, pesticide, dyes, sparingly soluble engineering plastic and refining of petrochemical industry, etc
Up to now, we have got the certificates of ISO9001, ISO14001 and SGS (RoHS, New Restricted Substance and non-halogen). As to Reach Registration, we are now in the stage of SIEF. Because of manufacturing characteristics of products, we adopt DCS to supervise and control all procedures of production, which provides a strong guarantee for the consistency of the process, performance of products, security of production and reduction of cost.
