Phenolics are hard, dense materials made by applying heat and pressure to varying weighted layers of paper, cotton, or a glass fabric mix that is impregnated with a synthetic resin. Phenolics are approximately half the weight of aluminum and their physical toughness resists abrasion, friction, as well as impact and material fatigue.
In addition to their machinability, phenolic also has low water absorption and dissipation factors, corrosion resistance to 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 number of fabricated parts. By using special flame retardant epoxy resins, phenolic can be given superior flame resistance.
Common applications for phenolics include terminal boards, antenna insulators, printed circuit boards, washers, spacers, cams, inserts, bushings, gaskets, rings, collars, switch gears, violent storm or ballistic protection, textile bobbins, lap spools and structural parts that require good impact strength or where size-to-strength ratio is critical.
Piedmont Plastics offers a wide variety of phenolic sheet including XX, CE, LE, and G-10 in varying gauges and sheet sizes ranging from 36” x 48” to 48” x 120”. We also carry phenolic rod and tubing with varying diameters and wall thicknesses and in lengths up to 48”. We are prepared to meet your phenolic needs for nearly every application.
