Phenolics are an industrial plastic that have a number of industrial applications. They are typically used for insulation and electrical applications.

Phenolic plastic is created from a mixture of different substances such as silicone, phenolic, melamine and other materials using heat and pressure. Phenolic plastic has phenomenal resistance to heat, stress, and certain corrosive chemicals. Phenolics are typically used for insulation and electrical applications.


In addition to its machinability, phenolic material also has low water absorption and dissipation factors, resistance to corrosion for a number of chemicals, and superior electrical characteristics exhibited over a wide range of temperatures and humidity. These material qualities make phenolics ideal for use in a wide variety of fabricated parts. In addition, by using special flame retardant epoxy resins, phenolic materials can be given superior flame resistance.
