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.

Composed of a continuous glass woven cloth base impregnated with a silicone resin binder, this grade has excellent heat and arc resistance. It has extremely good dielectric loss properties under dry conditions and good electrical and good electrical properties under humid conditions, although the percentage of change is high.
