Product Usage

Sodium formate is an important organic salt with a wide range of applications. In the leather industry, it is used as a masking agent for chromium tanning, helping chromium salts penetrate evenly and improving the softness and heat resistance of leather. In the textile and dyeing industry, it serves as a leveling agent and reducing agent for strong acid dyes, promoting even dyeing and preventing dye oxidation. In the construction industry, it is used to produce environmentally friendly concrete set accelerators, shortening cement setting time and improving construction efficiency in winter. In the chemical industry, it is an important intermediate for producing formic acid, oxalic acid, and sodium dithionite. Additionally, it is used as a drilling fluid additive in oil drilling, with minor applications in food and pharmaceuticals. Its advantages include mild properties, low corrosivity, and good biodegradability.
