Bisphenol A-type diether dianhydride (BPADA), CAS 38103-06-9

Key synthetic monomers for high-performance polyimide (PI), 5G high-frequency, high-speed flexible copper-clad laminates (FCCL), OLED flexible substrates, and lightweight composite materials for aerospace applications.

It contains highly reactive anhydride groups and is extremely sensitive to moisture. Upon contact with water, it readily undergoes hydrolytic ring-opening to form a dicarboxylic acid, thereby significantly reducing or completely eliminating its polymerization activity. It must be stored under absolutely dry, hermetically sealed conditions. Polymerization is recommended to be carried out under an inert gas atmosphere (such as nitrogen or argon) in anhydrous polar solvents (such as NMP or DMAc).

Jiangsu Juming Chemical Technology Co., Ltd. was established in November 2017 and is an integrated enterprise encompassing R&D, production, trade, and diversified services. The company is headquartered in Jiangyin City, Jiangsu Province, with production bases located in Shandong, Hebei, Henan, and Hubei Provinces in China. It currently employs 1,000 workers and operates a state-of-the-art laboratory equipped with four gas chromatographs and eight liquid chromatographs. The company primarily manufactures and markets electronic-grade chemicals, water treatment agents, UV absorbers, agrochemical and pharmaceutical intermediates, and other fine chemical products, which are widely sold in Europe, the United States, Japan, South Korea, and numerous other countries and regions. Its core products include 5-methylbenzotriazole, with an annual output of 2,000 metric tons, and 1,2,3-benzotriazole (BTA), with an annual output of
Annual production capacities include 3,000 tonnes of [unspecified product], 2,000 tonnes per year of sodium benzotriazole (BTA-Na), 3,000 tonnes per year of methylbenzotriazole (TTA), 2,000 tonnes per year of sodium methylbenzotriazole (TTA-Na), 2,000 tonnes per year of carbohydrazide (carbonyl hydrazine), and 2,000 tonnes per year of benzophenone (BP). These products are widely used in water treatment, chemical intermediates, agrochemicals, pharmaceuticals, UV absorbers, fertilizers, textile dyeing and printing, flame-retardant additives for fireproof materials, and the production of magnesium salts. We hold ISO 9001 certification, SGS certification, and CMA testing accreditation, and we are recognized as a contract-abiding and trustworthy enterprise.
Since its establishment, the company has earned unanimous recognition from numerous clients and enjoys a stellar reputation that continues to grow by word of mouth. The team at Juming is committed to forging sincere partnerships with colleagues across society to achieve shared success and brilliance!
