Phenolics have … Phenol formaldehyde resins (PF) or phenolic resins (also infrequently called phenoplasts ) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics). They have been … See more 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 … See more Base-catalysed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of greater than one (usually around 1.5). These … See more Phenolic resins are found in myriad industrial products. Phenolic laminates are made by impregnating one or more layers of a base material such as paper, fiberglass, or cotton with phenolic resin and laminating the resin-saturated base material under heat … See more Phenol-formaldehyde is degraded by the white rot fungus Phanerochaete chrysosporium. See more Novolaks (or novolacs) are phenol-formaldehyde resins with a formaldehyde to phenol molar ratio of less than one. In place of phenol itself, they are often produced from cresols (methylphenols). The polymerization is brought to completion using … See more When the molar ratio of formaldehyde:phenol reaches one, in theory every phenol is linked together via methylene bridges, generating one single molecule, and the … See more • Bakelite was originally made from phenolic resin and wood flour. • Ebonol is a paper-filled phenolic resin designed as a replacement for ebony wood in stringed and woodwind instruments. • Novotext is cotton fibre-reinforced phenolic, using randomly oriented fibres.
