Formic Acid
HCOOH | CAS: 64-18-6 | HS: 29151100
Product Description
Formic Acid is the simplest carboxylic acid — a highly versatile organic acid with unique reducing properties alongside its acidity, enabling applications in leather tanning, rubber coagulation, textile dyeing, and silage preservation. In leather production, it is the primary pickling acid for hides before chrome tanning, and the pH-adjusting acid for penetration of chrome tanning liquors. Natural rubber coagulation with formic acid produces the large majority of the world's rubber from latex. In feed preservation, it inhibits fermentation and mould growth in high-moisture silage. MITCHEM exports multiple concentration grades with full safety documentation.
Applications by Industry
Primary pickling acid for hides and skins before chrome tanning; provides controlled acid environment for chrome complex penetration and fixation in the leather matrix.
Coagulating agent for natural rubber latex — the majority of global natural rubber sheet is produced by formic acid coagulation of Hevea latex in rubber plantations.
pH regulator in acid dye baths for wool, silk, and nylon dyeing; promotes dye exhaustion and level dyeing at controlled pH in batch and continuous processes.
Applied as a feed preservative and silage acidulant to inhibit spoilage microorganisms, control pH, and preserve high-moisture grass and maize silage for ruminant nutrition.
