Phenolics & Industrial Laminates

Among the oldest plastics on the market, phenolics & industrial laminates are thermoset plastics, meaning they cannot be altered by heat. They are typically made from a combination of resins and fillers such as paper, linen and canvas, have good electrical and mechanical properties and are resistant to heat, flame and chemicals.

  • Dimensionally stable - Many variations of the basic material.
  • 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 Sheets – Thicknesses from 0.01" to 5". Standard sheet sizes are 36" x 48", 48" x 48" and 48" x 96".
