Potassium Formate (For Carbon Black) Manufacturers, Exporters & Suppliers - Innovacorp India Pvt Ltd in Greater Noida

Potassium Formate (Carbon Black Grade) is a specialized structural inhibitor used in the furnace black process to control the Oil Absorption Number (OAN). In Greater Noida’s thriving automotive and mobile component industries, this grade is essential for producing high-quality carbon black used in precision rubber seals, gaskets, and polymer casings. It ensures uniform particle structure and ultra-low ash content, providing high-durability materials for the manufacturing giants located in the Ecotech industrial zones.

Role in Carbon Black Production

Carbon black is produced by the incomplete combustion or thermal decomposition of hydrocarbons. During manufacturing, additives like potassium formate improve reaction efficiency, enhance product quality, and provide process stability.

In carbon black production, especially in specialty carbon blacks and high-quality carbon blacks, structural inhibitors play a pivotal role. Before the 1990s, sodium hydroxide was generally used as a structural inhibitor; with the development of special carbon black, it was gradually replaced by potassium carbonate; however, due to the low solubility of potassium carbonate, it is easy to layer after dissolution (the upper and lower concentrations in the solution tank Non-uniformity), which leads to easy clogging of the nozzle and unstable quality of carbon black. Since 2004, we have cooperated with a multinational carbon black company in the United States to replace potassium carbonate with potassium formate for experimental production of carbon black.

The effect is very good. Through nearly ten years of promotion, potassium formate has become the mainstream of structural inhibitors in carbon black production. At the same time, the ash content in carbon black production is also a very important indicator. Therefore, in order to ensure that the ash content in carbon black meets the standard, certain requirements are also set for the toxic and harmful substances in potassium formate.
