Phenol formaldehyde resins (PF) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Phenolic resins are mainly used in the production of circuit boards. They are better known however for the production of molded products including pool balls, laboratory countertops, and as coatings and adhesives. In the form of Bakelite, they are the earliest commercial synthetic resin.
Applications
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 and
pressure. The resin fully polymerizes (cures) during this process.
The base material choice depends on the intended application of the
finished product. Paper phenolics are used in manufacturing
electrical components such as punch-through boards and household
laminates. Glass phenolics are particularly well suited for use in
the high speed bearing market. Phenolic micro-balloons are used for
density control. Snooker balls as well as balls from many
table-based ball games are also made from phenol formaldehyde
resin. The binding agent in normal (organic) brake pads, brake
shoes and clutch disks are phenolic resin.
