Phenolic - PF Phenol Formaldehyde

Advantages

Low cost basic resin. Addition of appropriate fillers can generate high temperature resistant grades (185°C/370°F).  Normal Phenolics resistant to 150°C/300°F. Low smoke emission.

Disadvantages

Tends to be brittle with normal low cost fillers.  Only available in dark colours.  Certain resin formulations not resistant to alkalies.  Humidity badly affects tracking resistance.

Applications

Mouldings: Electrical & mechanical fittings, e.g. handles, plugs, sockets, connectors (although replaced by urea’s for domestic market).  Bottle tops.

Resins: Adhesive/binder for chipboard, plywood. Chemically resistant coatings for metals.

Laminates: General industrial use (Tufnol), PCB, water lubricated bearings.

Foam: Thermal insulation.
