Shanghai Milin Chemical Co., Ltd. was registered and established in Shanghai, China in early 2006. In 2010, Shanghai Haolin Chemical Co., Ltd. was founded in Jinshan, Shanghai, and in 2022, Haolin (Weihai) New Materials Co., Ltd. was established in Shandong. Since its establishment, Milin and Haolin Chemical have been dedicated to the research and production of cutting fluid additives for over a decade. We focus on independent research and production rather than acting as agents for foreign brands; we emphasize core competitiveness rather than expanding our product range by stocking market goods. We advocate for quality over quantity. Milin Chemical is labeled as a domestic manufacturer of cutting fluid additives rather than a trader. Compared to our competitors, our product range is less than one-tenth of theirs. However, our quality and prices are highly competitive. Milin is a genuine additive manufacturer.
At the beginning of its establishment, Milin Chemical was the first in China to independently develop and produce biocide BK and biocide MBM, which remain the brands of mainstream cutting fluid manufacturers in the country. In 2010, Milin Chemical achieved independent production of ternary carboxylic acid rust inhibitors, with key performance close to advanced international levels. In 2014, Milin Chemical developed an aluminum corrosion inhibitor with performance comparable to mainstream foreign products, with an additive dosage as low as 0.4%.
Milin Chemical has many years of experience in the development, research, and on-site application of metalworking fluids and additives, offering unique insights into additive recommendations and production technology based on application formulas. Our products include: lubricants, biocides, rust inhibitors, defoamers, phosphate ester aluminum alloy corrosion inhibitors, and other single agents.
Currently, Milin Chemical has become a long-term partner of major domestic metalworking fluid manufacturers, witnessing the development of China's independent metalworking fluid brands!
