Phenolics

(Industrial Laminates)

Phenolics, which are among the oldest plastics on the market, are thermoset plastics. Unlike thermoplastics that can change shape when heated, a thermoset plastic cannot be altered by heat.

Phenolics are typically made from a combination of resins and fillers such as paper, linen and canvas. They have good electrical characteristics and are resistant to heat, flame and chemicals.

Because phenolics are dimensionally stable, they are often formulated to meet specific requirements such as high electrical resistance. As a result, there are many variations of the basic material.

Phenolic is part of a larger family of “Industrial Laminates” that include glass/melamine and glass/epoxy configurations. Melamines are the hardest laminates made and are known for their arc resistance (G-5, G-9). Epoxy is used for its excellent electrical and mechanical properties in both wet and dry conditions (G-9, G-10 and FR-4).

Phenolic Applications

Typical Applications

Phenolic plastics, and related industrial laminates, are used for such applications as:

  • Clutch facings
  • Decorative laminates
  • Ducting
  • Electrical insulators
  • Grating
  • Terminal blocks
  • Switches
  • Motor components
  • Arc Barriers
  • Switchboard Panels
  • Circuit beaker parts
