Phenolic G10 glass epoxy rod 1.250" diameter x 4 ft
Phenolic Laminates are made by applying heat and pressure to layers of paper, canvas, linen or glass cloth 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 - therefore, 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.
G-10 and G-11 (Glass Cloth / Epoxy Resin)
These glass-epoxy laminates are specified for their extremely high strength and high dimensional stability over temperature. G-10 and G-11 are used for terminal boards, high humidity applications, electrical and electronic test equipment and electric rotor insulation. G-10 and G-11 are difficult to cut or machine and may require special equipment. 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.
