Investigation of a commercial fire-retardant additive on particleboard properties
2025 - IRG/WP 25-20755
Fire resistance of wood-based panels is in addition to mechanical and sorption properties, an important property when considering its usability for construction applications. Increased fire resistance is achieved through fire retardant addition during panel production or by spraying fire-retardant on already finished panel. A potential downside of fire-retardant addition during panel production ca...

Optimising properties of citric acid-sorbitol bonded particleboards with added ammonium dihydrogen phosphate as fire retardant
2025 - IRG/WP 25-41033
Due to the adverse health effects of formaldehyde-based adhesives and their fossil origin, there is an ongoing search for appropriate bio-based adhesives for particleboards. Although there are some possible solutions, their use in construction is limited partly due to their low moisture resistance and flammability. The latter can be improved by adding various fire retardants. A particleboard with ...

Preliminary assessment of imidazole as an adhesion system for particleboards
2025 - IRG/WP 25-41043
Particleboards with different combinations of adhesive mixtures containing imidazole, citric acid, and sorbitol were produced. Softwood sawdust from a Swedish sawmill was mixed with an aqueous solution of the chemicals and then dried to 0% moisture content prior to pressing. The boards were pressed to a target density of 700 kg m−3 at either 200 °C or 220 °C for 10 min. The hygroscopic and mec...
