WebPhenolic resins were first made in 1872 when Adolph Baeyer reacted phenol with acetaldehyde. Bakelite phenolic resins were developed by Leo Baekeland beginning in 1907. Examples of phenolic resins are Bakelite, Novolac and Catalin. Phenolic resins are used for molded parts, as adhesives and as varnishes. See also phenol formaldehyde . WebSince 1907, when Leo Baekeland created the first synthetic thermosetting plastic, the Bakelite® brand has stood for the finest phenolic resins and molding compounds – …

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 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phenol is linked together via methylene bridges, generating one single molecule, and the … See more • Bakelite was originally made from phenolic resin and wood flour.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. See more Novolaks (or novolacs) are phenol-formaldehyde resins with a formaldehyde to phenol molar ratio of less than one.
