High-Temperature Garolite G-11 Sheets and Bars

Offering higher strength and better heat resistance than Garolite G-10/FR4, these Garolite G-11 sheets and bars are suitable for continuous use in elevated temperatures. They retain at least 50% of their structural strength at temperatures above 300° F. Made of an epoxy resin with fiberglass fabric reinforcement, Garolite G-11 is sometimes called epoxy-grade industrial laminate and phenolic.
