Glass Epoxy Phenolic

B.I.R.S. Machine & Supply is a distributor of Glass Epoxy Phenolic

Glass cloth epoxy phenolic is impregnated with synthetic thermosetting resins. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the separate layers into a single laminated material with a set shape that cannot be softened again. These materials are called "Thermosets". A variety of resin types and cloth materials can be used to manufacture thermoset laminates with a range of mechanical, thermal, and electrical properties.

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. "FR" grades are flame retardant. Glass-based grades have the highest dimensional stability and mechanical strength, as well as low moisture absorption. However, they are not as easily machined as paper or cotton fabric laminates.

Glass epoxy phenolic laminates are specified for their extremely high strength and high dimensional stability over temperature. G-10 and G-11 are used for high humidity applications, electrical and electronic test equipment and electric rotor insulation. G-10 is slightly stronger while G-11 is a better insulator and can take higher temperatures. FR-4 is a fire-retardant G-10 glass-epoxy laminate that is used primarily in the printed circuit board industry.
