GBL serves as a chemical intermediate in the manufacture of all pyrrolidones. It can be used in the production of pesticides, herbicides and plant growth regulators. GBL may be formed as an intermediate in the production of vitamins and pharmaceuticals. As a solvent, GBL can be used in/with: · pesticides · photochemical etching · electrolytes of small batteries or capacitors · viscosity modifiers in polyurethanes · surface etching of metal coated plastics · organic paint disbursements for water soluble inks · pH regulators in the dyeing of wool and polyamide fibers · foundry chemistry as a catalyst during curing · curing agents in many coating systems based on urethanes and amides 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. please find our sales specification as follows: Test Item Specification Test Result Appearance Clear Liquid Clear Liquid Purity(wt%, GC) ≥99.9 99.91 Water Content(wt%, K.F.) ≤0.03 0.021 Color(APHA, Pt/Co) ≤10 8 Density(D420g/ml) 1.125-1.135 1.1252 Refractivity(ND20) 1.436-1.438 1.4363 Metal Contents Specification Test Result Butanediol Content(%) ≤0.1 THF Content(%) ≤0.05 Acidity(Butyric Acid)(%) ≤0.03 Cl- (ppm) ≤0.3 SO42- (ppm) ≤1.0 NO2- (ppm) ≤1.0 Fe (ppb) ≤50 Cu (ppb) ≤50 Zn (ppb) ≤50 Pb (ppb) ≤50 Na (ppb) ≤50 K (ppb) ≤50 Remark If you are interested in our product, please feel free to let me know.
