What Is Formaldehyde Used For

Formaldehyde is primarily used in the production of industrial resins and adhesives, especially for wood products such as particleboard, plywood, fiberboard, and engineered wood used in furniture, cabinetry, flooring, countertops, and other building materials[1][2][3][4][5].

It also plays an essential role in the manufacture of coatings, insulation materials, and paper product finishes[1][4].

Formaldehyde’s reactivity allows it to form durable polymers, contributing to strong adhesives and versatile construction materials that offer heat, chemical, and moisture resistance[5][7].

In healthcare, formaldehyde is used as a preservative for biological specimens, vaccines, and medical equipment, as well as a disinfectant and antiseptic[1][6][7].

The textile industry uses formaldehyde-based resins to enhance fabric properties—improving crease-resistance, colorfastness, and overall durability in both clothing and industrial textiles[3][7][8].

Formaldehyde is a component in automotive and aerospace manufacturing, providing lightweight, high-performance resins for interior parts, brake pads, coatings, and insulation[1][5][7].

In agriculture, it serves as a pesticide, fungicide, seed preservative, and soil treatment agent[6].

Other applications include serving as a chemical intermediate in producing plastics, paints, explosives, polyurethane foams, and pharmaceuticals[3][6].

Death care industries rely on formaldehyde as a principal embalming fluid to preserve bodies for medical study and ceremonies[6].

Formaldehyde and its derivatives may also be found (in small, regulated quantities) in personal care and cosmetic products as preservatives, and indirectly in food-contact materials for disinfecting containers, although use as a direct food additive is illegal in many jurisdictions[1][7].
