About us

Our technology development department is principally engaged in the chemical formula analysis, component analysis, component testing, process development, technology transfer and other related technology services. We have small scale pilot laboratory, scale-up pilot workshops and a team of experienced researchers and engineers. After several years of involvements in this field, we have accumulated a wealth of experience in the lab development, scaling up, and final production process design. By now tens of  large-scale chemical production process designs, plus hundreds of new chemical products developments, lab technology research and the resolving of industrial problems have been accomplished in LONGO CHEM.
