Unlike softwood plywood panels which are not bound by the formaldehyde emission restrictions set by the California Air Resources Board (CARB), hardwood plywood (composite or veneer core) panels, curved plywood panels and composite wood panels such as particleboard and MDF, must conform to strict guidelines before the products can be sold and used.
Abstract Three particleboard types, including urea-formaldehyde (UF), melamine-formaldehyde (MF), and binderless, were made from three wood species, sengon (Paraserianthes falcataria), gmelina (Gmelina arborea), and mindi (Melia azedarach).
16 /PRNewswire/ - Uniboard, a leading North American manufacturer of engineered wood products, is pleased to announce that it has been approved as a manufacturer of Ultra Low Emission Formaldehyde (ULEF) particleboard by the California Air Resources Board (CARB).
A 3-inch-square coating emitted far more formaldehyde--between 50 and 800 micrograms--than did an equal area of particleboard or veneer-covered plywood, the Battelle scientists report in the Jan.
Today, however, the levels of formaldehyde found in the resin used in particleboard have been drastically reduced -- by almost 80 percent.
ISOBORD[TM] is an exciting and competitively priced alternative to the traditional wood particleboard used under an overlay in most furniture and kitchen cabinets.
Manufacturers must demonstrate compliance with stringent criteria to be awarded ESP certification, including: * 75% of particleboard, plywood and MDF must be certified to meet the lowest formaldehyde emission standards; * 75% of particleboard and MDF used must contain 100% recycled or recovered fiber content; * Hardwoods must be certified through an independent and credible forestry program; * A documented energy conservation program must be in place; * A written Environmental Management System must be available and enforced; * A recycling program for process wastes must be in place; * All federal, state and local environmental requirements must be observed; and * Community involvement and leadership through service or charitable organizations must be part of the company's culture.
Abstract Two experiments were performed to determine the physical and mechanical characteristics of panels consisting of a veneer face and a particleboard core composed of mixed wood particles/powdered-recycled polyethylene (PE) bag waste (MWP) using urea-formaldehyde (UF) resin as a binder.
