Static-Dissipative Multipurpose Flame-Retardant G-11/FR5 Garolite Sheets

Offering higher strength and better heat resistance than Garolite G-10/FR4, these Garolite G-11/FR 5 sheets are suitable for continuous use in elevated temperatures. With a black coating that reduces static electricity, these sheets are good for use in solder pallets, automated test equipment, electronic assembly workstations, and other applications where static buildup could damage your equipment. The coating is cured, so it won’t chip or peel off. These sheets are made of flame-resistant epoxy resin and are easier to machine than other glass-cloth phenolics. A fiberglass fabric reinforcement keeps them from breaking or cracking when bent. Sheets vary in shade from yellow-brown to light green.
