The phenolic resins are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, they were the first commercial synthetic resins (plastics). This step-growth polymerization reaction can be either acid- or base-catalyzed. In acid, the reaction forms novolac resins. These resins require a curing agent – often hexamethylenetetramine or hexa. They are not heat-sensitive. In alkaline solution, the polymerization reaction produces resole resins. These resins are sensitive to heat and acids, do not require curing agents, and have relatively short shelf lives.
The most important use of phenolic resins is the production of plastic laminates. The materials may be various: wood chips, paper, cloth, sand, glass fiber. The phenolic resin may constitute a small part of the total. The laminates are used as the floors of work tables, but also to more valuable uses: floors, doors, pieces of equipment, supports for printed circuits.
