Phenolic
resin is produced by a condensation reaction involving a phenol
and an aldehyde. A major application for phenolic resin is in the
production of copper clad electrical laminates. Due to their high
aromatic content phenolic resins are considered to have low flammability
and as a consequence of this end uses include brake linings and
foamed insulation for pipes.
However,
in the electrical laminate industry layers of flammable Kraft paper
are pressed within the phenolic laminate necessitating the use of
Reofos ® and Kronitex ® or Firemaster 550 flame retardants
to achieve the usual FR-2 flammability classification. A further
benefit with the incorporation of above liquid flame retardants,
leads to plasticisation of the phenolic laminate, giving rise to
enhanced flexibility which also improves the cold punchability of
the laminate.
