Life-cycle inventory (LCI) data are needed to scientifically document the environmental performance of formaldehyde-based resins used in the manufacture of wood composite products. The resin data are needed by others to conduct LCI studies of wood composites when providing performance data for applications as governed by the many green building standards, purchasing guidelines, and energy and c...

The development of natural-based adhesives is a key aspect in reducing the consumption fossil resources, adapting to legislation on use formaldehyde and ensuring sustainability wood panel industry. This study focuses five alternatives for tannin-based (tannin-paraformaldehyde, tannin-glyoxal, tannin-hexamine, tannin non-isocyanate polyurethane (NIPU) with ammonium hydroxide NIPU HDMA bio-adhesi...

Composites based on waste products from the production of 5-hydroxymethylfurfural - "humins" and melamine or urea (as a cross-linking agent) with wood fl our filler, 70 % by weight) were obtained. Studies physical mechanical properties materials different contents have been carried out, which shown that composites humins: (2,5: 1) humins:urea (2:1) tensile strength 150 165 MPa, respectively, si...

In a multicentre study consecutively patch-tested dermatitis patients were tested simultaneously with 1.0% and 2.0% (w/v) formaldehyde in aqua applied with a micropipette (15 µl) to the filter paper disc in Finn Chambers (0.30 mg/cm(2) and 0.60 mg/cm(2), respectively). A total of 2,122 dermatitis patients were patch-tested. In all, 77 (3.6%) patients reacted positively to formaldehyde; 37 react...

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...
