  • Phenol formaldehyde resin Wikipedia

    Phenol formaldehyde resins (PF) or phenolic resins 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 widely used for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives.

  • Fenolhars Wikipedia

    Fenolhars is een kunsthars verkregen door de condensatiepolymerisatie van fenol met formaldehyde.De polymerisatie kan zowel met een zure als een basische katalysator gebeuren. Zure katalysatoren zijn bijvoorbeeld zwavelzuur of oxaalzuur.Basische katalysatoren zijn bijvoorbeeld kalk, ammoniak of aniline.In de plaats van fenol kan men ook een alkylfenol gebruiken zoals nonylfenol of p-tert

  • Fenol Wikipedia

    Fenol of hydroxybenzeen, vroeger ook wel carbolzuur of carbol genoemd, is een organische verbinding bestaande uit een benzeenring waarvan één waterstofatoom is gesubstitueerd door een hydroxylgroep (OH). Fenol is daarom een aromatische alcohol.In oudere teksten wordt fenol soms benzol genoemd, al is dit een germanisme: Benzol is de Duitse benaming voor benzeen.

    Les phénoplastes ou « résines phénol-formaldéhyde » (sigle PF) sont issus du formaldéhyde et du phénol.Ils font partie de la famille des polymères thermodurcissables.Le phénol étant un monomère trifonctionnel (la molécule monomère possède trois sites actifs), il se forme finalement un réseau tridimensionnel [2].. Un exemple bien connu est celui de la « bakélite » (marque

  • Phenol-Formaldehyde Resin

    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.
