Phenolics, also known as Thermosets, are extremely versatile machinable plastics that deliver unique properties by combining resins with composite materials.



Phenolics, also known as Thermosets, are extremely versatile and machinable plastics that deliver unique properties by combining resins with composite materials. These composites include glass fiber, canvas, woven cotton and paper, blended with phenolic or epoxy resins, and resulting in materials with high strength and stiffness. Phenolics/thermosets have varying properties depending on the reinforcement material used.

Phenolic plastics are tough, light in weight, and corrosion resistant, and their insulating qualities include low dissipation factor and excellent dielectric strength, making them an ideal material for a variety of electrical and electronic applications. Certain grades of phenolics can also deliver exceptional flame resistance, through the incorporation of specially-formulated flame-retardant epoxy resins.
