Formaldehyde in plywood


Formaldehyde releases into the air from many sources. Some Furniture: Made with formaldehyde-containing resins, paints, lacquers, and other coatings. Composite Wood Products: Particle board, plywood, and fiberboard are often made with formaldehyde-containing resins and are used in furniture, cabinets, shelves, doors, wall and flooring materials. Since 2005 we’ve been manufacturing our hardwood plywood using a formaldehyde-free adhesive derived from food-grade soy flour and a wet strength resin used in printed currency and milk cartons. This proprietary assembly system, known as PureBond, is cost-competitive with urea formaldehyde based plywood products. XWet process fibreboard (unfaced), when no formaldehyde emitting resin has been added to the process Xunfaced, coated or overlaid wood based panels glued with resins emitting either no formaldehyde or negligible amounts of formaldehyde after production as e.g. isocyanate, or phenolic glue. Formaldehyde is a chemical with many industrial applications; one of the largest of these is in plywood. According to www.turi.org 1 , about 64% of the formaldehyde produced worldwide is used in plywood or other wood products such as particleboard. The resin used to make most manufactured wood products is formaldehyde-based. 7-ply hardwood plywood panel is assembled with smooth, patch-free decorative maple veneers; PureBond hardwood plywood is an environmentally friendly, cost-competitive alternative to panels manufactured with urea formaldehyde (UF), which may degrade air quality over time
