Physical strength, resiliency, ease and versatility of fabrication, and excellent electrical properties make Phenolic Laminates useful as support components in a wide range of mechanical and electrical applications. Phenolic Laminates are strong, stiff, and have high impact and compressive strengths. And they do not soften upon re-heating, so they are easy to saw, drill, tap, and machine with ordinary tools.
Medium weave cotton cloth fabrics are mixed with phenolic resins to provide good wear resistance, low moisture absorption, and good mechanical strength at economical cost. Canvas-based phenolics are used for structural supports, piston rings, gears, spacers, and bearing surfaces.
