Composite wood products have traditionally relied on thermosetting polymers like phenol-formaldehyde and urea-formaldehyde resins as binders. The continuing need to effectively utilize lignocellulosic fiber from lowquality hardwoods and from recycling streams has prompted consideration of new composites based on thermoplastic polymers [ 1,2]. Much of the development effort has focused on commod...

Background The issue of formaldehyde exposure in homes is long-standing and has been studied over time. Formaldehyde is frequently used in plywood, fiberboard, resins, glues, and several other construction components. In the past, formaldehyde was also used in insulation of many homes. In March of 1982, the U.S. Consumer Product Safety Commission (CPSC) called for a ban on urea foam formaldehyd...

Abstract: (MGG’) resin adhesives for bonding wood panels were prepared by a single step procedure, namely reacting melamine with glyoxal and simultaneously with a much smaller proportion of glutaraldehyde. No formaldehyde was used. The inherent slow hardening of this resin was overcome by the addition of N-methyl-2-pyrrolidone hydrogen sulphate ionic liquid as the adhesive hardener in the glue ...

BACKGROUND Preservatives present in cosmetics and other industrial products can cause allergic contact dermatitis. The aim of the study was to assess the frequency of allergy to selected preservatives in consecutive patients examined due to contact dermatitis in the Nofer Institute of Occupational Medicine, Łódź, and to establish whether individuals sensitized to formaldehyde react simultaneous...
