Phenol formaldehyde resin - Wikipedia

Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid - or base -catalysed. Since formaldehyde exists predominantly in solution as a dynamic equilibrium of methylene glycol oligomers, the concentration of the reactive form of formaldehyde depends on temperature and pH.

Performance and characterization of phenol-formaldehyde resin

In order to clarify the effects of crude bio-oil for phenol-formaldehyde resin, the phenol-formaldehyde resin with bio-oil model compounds (BMPF) were prepared by model compound method. The bonding strength and aging resistance of BMPF were determined, and their microstructure and chemical bonds were also analyzed by scanning electron microscope, Fourier transform infrared spectroscopy, and ...

Frontiers | High Temperature Composites From Renewable

Phenol-formaldehyde resins are synthetic polymers obtained by the reaction of phenol and formaldehyde. The molar ratio between these two organic compounds and the acidity (or basicity) of the environment in which they are allowed to react can lead to various and versatile families of phenolic resins (Gardziella et al., 2013). Heat reactive ...
