Wuxi Zhengmao Chemical Co., Ltd., founded in the 1970s, is a fine chemical company supporting auxiliary production for the petrochemical industry, specializing in the production of polyester catalysts, polymerization inhibitors, antioxidants and other products.
Main products: polyester catalyst ZM-24 (ethylene glycol antimony), polyester catalyst antimony trioxide, industrial grade antimony trioxide, polymerization inhibitor p-hydroxyanisole, phenothiazine, p-tert-butyl catechol (TBC), NN-copper di-n-butyldithiocarbamate (AI-61R), antioxidant ZM-405 (similar to NAUGARD445), etc.
The antimony trioxide used for polyester catalysis produced by the company is the first domestic product to replace imported products and is ideal for long-term stable application in imported equipment. In 1999, it successfully developed a new high-activity polyester catalyst ZM-24 (ethylene glycol antimony) with international standards, and applied for a national patent. Passed the appraisal of scientific and technological achievements organized by Jiangsu Science and Technology Commission on December 8, 1999. The products have been continuously applied to the polyester plant of China Jinan Chemical Fiber Corporation and Shanghai Petrochemical Co., Ltd., and all technical indicators have reached the international advanced level of similar products, replacing imports. In September 2000, it was recognized as a high-tech product by the Jiangsu Provincial Department of Science and Technology, and was included in the 2001 Jiangsu Torch Plan project. It was rated as "1998-2000 Excellent New Product of Jiangsu Province (Golden Bull Award) by the Jiangsu Economic and Trade Commission In September 2001, it was approved as a national torch plan project by the Ministry of Science and Technology and won the "Gold Award" at the International (Tianjin) Invention, Patent and New Technology and New Products Expo. In 2003, it developed its own antioxidant ZM-405, which was used in the polyether production facility of Shanghai Gaoqiao Chemical Company, and reached the quality level of imported antioxidant NAUGARD445. Polyester catalyst antimony trioxide, polymerization inhibitor p-hydroxyanisole, phenothiazine won the "Gold Award" of China Patent Technology Expo in 1994, the "Gold Award" of the Third China International New Technology and Famous Products Expo in 1997, Jiangsu Province "Third Prize" for scientific and technological progress. Among them ZM-24 (ethylene glycol antimony), antimony trioxide, p-hydroxyanisole, phenothiazine, p-tert-butylcatechol (TBC), NN-di-n-butyl copper dithiocarbamate (AI -61R) 6 products were designated as recommended products by Sinopec and PetroChina. Product marketing throughout the country, exported to overseas, well received by users.
