G-11 Fiberglass Epoxy Laminate Sheet
Categories:	Polymer; Thermoset; Epoxy; Filled/Reinforced Thermoset
Material Notes:	This glass-epoxy laminate is specified for its extremely high strength and high dimensional stability over temperature. G-11 is used for terminal boards, high humidity applications, electrical and electronic test equipment and electric rotor insulation. G-11 is difficult to cut or machine and may require special equipment. G-10 is slightly stronger while G-11 is a better insulator and can withstand higher temperatures. G-11 and similar fiberglass reinforced thermosets are sometimes known as garolite. Information provide by Boedeker Plastics.
