It's in the resins used to make most particle board, plywood, and wood paneling; the foam in urea-formaldehyde insulation; the sizing applied to upholstery and drapes; the adhesives used with carpeting and wallpaper; the "permanent press' resin in clothes; the germ killer in toothpaste--and the ink in the dollar bills that pay for all these things. The chemical bond between the urea and formaldehyde is weak, resulting in degradation of the foam cells and emission of toxic formaldehyde gas into the home over time. Most investigative studies of UFFI have concentrated on formaldehyde. Formaldehyde is a human toxicant with a long history of use in residential insulation. How common is UFFI? Numerous studies were conducted since, and it is believed that even after 30 years the UFFI foam still produces low levels of formaldehyde.
