Usos documentados

• Formaldehyde is used predominantly as a chemical intermediate. It also has minor uses in agriculture, as an analytical reagent, in concrete and plaster additives, cosmetics, disinfectants, fumigants, photography, and wood preservation. One of the most common uses of formaldehyde in the U.S is manufacturing urea-formaldehyde resins, used in particleboard products.
• Used in the production of formaldehyde resins, plywood, particle board, paper, and urea-formaldehyde foam; embalmers and laboratory workers may be exposed to levels above 1 ppm; [LaDou, p. 502-3] The major industrial consumers of formaldehyde resins are molded plastic parts, decorative laminates, photographic film, and plywood paneling. High formaldehyde exposures were documented in carpet installers and parquet tile fitters. Formaldehyde also exists as a polymer (paraformaldehyde) and as a trimer (sym-trioxane or
