Fabric Phenolic Laminates

Fabric Phenolic Laminate sheets are made with various weights of woven cotton fabric, impregnated with specifically formulated phenolic resins, bonded together under heat and pressure to produce a thermoset composite.

Offers superior machining, punching, and chemical resistance characteristics under high temperature.

The parts made of fabric phenolic composites deliver a high MTBF (Mean-time Before Failure), quieter operation in lubricated and non-lubricated applications and long life in wear-prone applications.
