General Info

GPO-3 is a rigid fiberglass reinforced composite laminate with a polyester resin system, it is flame retardant and is used for general purpose electrical and/or mechanical applications where low cost is desired.

GPO-3 can withstand higher temperatures compared to GPO-1 or GPO-2 grades and exhibits better electrical characteristics. GPO-3 offers excellent dimensional strength, high impact strength, high strength, excellent electrical properties and good flame and smoke characteristics.

In the construction industry, GPO-3 is known as "Red Barrier Board." It is commonly used for construction applications involving electrical insulation, including phase and end barriers, electrical insulating and bus bar support, mounting panels in switchgear, transformer applications, antenna component bases, and electrically insulating spacers.

Haysite®, Glastic®, GPO-3

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
