Thermal stability of boron-containing phenol formaldehyde resin

A comparison of soft magnetic composites designed from different ferromagnetic powders and phenolic resins

“…The band at 461 cm −1 represents the deformation vibration of Si\O\Si, which is also clearly visible in the spectrum of PFRGT. The FTIR spectrum for the resole-type resin modified with boric acid was reported by Gao and co-workers [26]. According to this work, the apparent change in the PFRB spectrum in comparison with PFR spectrum is observable in the range 1180 cm −1 -900 cm −1 .…”

Boron-containing poly(vinyl alcohol) as a ceramic precursor

“…The ceramic residue at 500°C was $20 wt%. The PVAB precursor presented a better thermal stability than PVA, probably due to its cross-linking characteristic associated to the better thermal resistance of B-O compared to C-O bonds [18].…”

Physico-mechanical properties of plywood bonded with ecological adhesives from Acacia mollissima tannins and lignosulfonates

“…The European Physical Journal Applied Physics temperature [12,23]. However, when the pressure temperature achieves 170 • C we remark that the tensile measurement of plywood panels decreases to 2332 N. This result can be explained by the thermal degradation of the surface panels with the increase press temperature to 170 • C, because curing has already taken place.…”
