Description
Sodium formate is the sodium salt of formic acid. It is a white, free-flowing substance available in granular, powder, and aqueous solution forms. Sodium formate is known for its reducing properties and excellent solubility in water. Its main uses span across industrial, textile, construction, and de-icing sectors due to its buffering capability, corrosion inhibition, and cryoprotective effects.
In various industries, sodium formate acts as a pH regulator, accelerator in cement additives, and as a buffering agent in leather tanning. It also provides efficient and eco-friendly de-icing performance, making it a preferred choice in airport runway deicers and high-performance snow and ice melting products. It is biodegradable and compliant with REACH and GHS regulations.
