Technical Formalin
Technical formalin is a 37% aqueous solution of formaldehyde, produced by the reaction of formaldehyde with methanol. It typically contains 4–8% methanol, which acts as a stabilizer to inhibit the polymerization of formaldehyde.
Technical formalin is widely used in industry as a raw material for the production of synthetic resins, plastics, and organic synthesis products; in rubber and tire manufacturing; as an inhibitor in metallurgy and oil & gas industries; as a disinfectant and antiseptic in agriculture; and in textile, leather, and paper industries to enhance material properties such as durability, shrink resistance, and dimensional stability.

Technical formalin is a colorless, highly flammable liquid containing 37 ± 0.5% formaldehyde and 4–8% methanol (as polymerization inhibitor), manufactured for industrial use. At 20 °C, its density is 1.1121 g/cm³ when formaldehyde content is 37%. During storage, slight cloudiness or white precipitate may form — these dissolve upon gentle heating (not exceeding 40 °C).
Minimum order volume: 200 liters
Packaging: Jerrycans, drums, IBC totes, tanker trucks
Shelf life: 4 months from the date of manufacture
