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 … Zobraziť viac 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 Zobraziť viac Base-catalysed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of greater than one (usually around 1.5). These resins are called resoles. Phenol, … Zobraziť viac 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 system is entirely crosslinked. This is why novolacs (F:P <1) do not harden … Zobraziť viac • Bakelite was originally made from phenolic resin and wood flour.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.
