“…According to Ayrilmis et al [ 31 ], using impregnated wood can lead to the deterioration of resultant particleboard due to the change in the pH of wood, reduction in the number of hydroxyl groups available for bonding, and mechanical interference of salt. The outcomes of research regarding the production of boards from the particles impregnated with monoammonium phosphate, diammonium phosphate [ 32 , 33 ], Burnblock ® [ 34 ], borax, boric acid [ 35 ], and boric-acid–disodium-octaborate [ 36 ] confirm there negative influence. Therefore, it is necessary to develop a method of modifying resins to produce impregnated boards characterized by good strength properties.…”

Due to the fact that impregnation with fire retardant usually reduces the strength of the produced particleboards, this research was carried out to investigate whether it is possible to use phenol–formaldehyde (PF) resin modified using various amounts (0%, 5%, 10%, 15%, and 20%) of polymeric 4,4′-methylene diphenyl diisocyanate (pMDI) for this purpose. The need to optimize the addition of pMDI is particularly important due to health and environmental aspects and high price. Furthermore, the curing process of hybrid resins is still not fully explained, especially in the case of small loadings. Manufactured particleboards differed in the share of impregnated particles (50% and 100%). The mixture of potassium carbonate and urea was used as the impregnating solution. Based on the outcomes of hybrid resins properties, it was found that the addition of pMDI leads to the increase in solid content, pH, and viscosity of the mixtures, to the improvement in resin reactivity determined using differential scanning calorimetry and to the decrease in thermal stability in the cured state evaluated using thermogravimetric analysis. Moreover, particleboard property results have shown that using impregnated particles (both 50% and 100%) decreased the strength of manufactured boards bonded using neat PF resin. However, the introduction of pMDI allowed us to compensate for the negative impact of fire-retardant-treated wood and it was found that the optimal loading of pMDI for the board containing 50% of impregnated particles is 5% and for board made entirely of treated wood it is 10%.

“…Boards made from bagasse with a density of 190 kg/m 3 & 370 kg/m 3 have better sound absorption. Depith Bagasse Particle Board can be used as an alternative to synthetic-based commercial products for acoustic applications in building construction [4] [5]. Wheat straw can be used as a promising raw material for panel production with the use of a tannin-modified PF adhesive [6].…”

Coir fibre is extracted from the husk of coconut and is used in products such as floor mats, door mats, brushes and mattresses and in many applications. Here coir fibres are used to make particle boards of densities 300, 400 and 500 kg/m 3 using UF resin to determine its efficiency for interior applications like acoustic and thermal properties and also tested for Indian standard 3129. Noise Reduction Coefficient (NRC) of all the boards decreases with an increase in density. Maximum sound absorption coefficient for all three densities was found in the frequency range of 2500 to 30,000 Hz. Among three densities, 300 kg/m 3 board shows the maximum absorption coefficient at frequency 3000 Hz. The thermal conductivity results of all three densities boards increase with an increase in density. Modulus of Rupture for all three densities were meeting the requirement of standard. Results reveal that particle board manufactured from coir fibre can be used for acoustic and thermal insulation applications.
