Formaldehydemission von Lagenholz und Verbundplatten

For determination of formaldehyde release from plywood and composite boards test procedures applied for the testing of particleboard were examined. The formaldehyde content determined by perforator method permits conclusions to be drawn as to the expected formaldehyde relese. The corresponding correlation is given, the result of comparative examinations of plywood and composite boards from different manufacturers proves that the use of suitable urea formaldes adhesives and special hardeners and upon consideration of some technological pecularities, these materials can certainly be produced with a formaldehyde emission ≦0.1 ppm for their favoured use in furniture manufacturing.
