GPO-3 is a general purpose grade Random Weave Glass Polyester Laminate. It is composed of random mat (non-woven) fiberglass reinforcement held together by a polyester resin binder. GPO3 composite sheet offers arc and track resistance. It is malleable, and can be made into various shapes like sheets, tubes, rods, etc. Properties of GPO3 Fiberglass Laminate Tufflam® GPO-3 composites have high dielectric strength, high flexural strength, high impact strength, flame resistance, as well as arc and track resistance. Despite all these appreciable qualities, Tufflam® GPO-3 glass polyester is a low-cost laminate. It can withstand higher temperatures than GPO-1 or GPO-2, and has better electrical characteristics than them, as it is more flame-resistant than GPO-1, and more arc-and-track resistant than GPO-2. Applications of GPO3 Polyester Laminate include general purpose electrical insulation, Transformer Spacers, Transformer Supports, Transportation Components, Track Resistance, Terminal Boards and Tag Strips, Switchgears, Switchgear Link Bars, Punched Components, Phase Barriers, Busbar Supports, Mechanical Applications, Insulating Bushes, Spacers and Sleeves, Insulation for High Voltage Appliances, High Voltage (Oil submerged) appliances, High Temperature Components, Flame Retardant Applications, Chemical Resistance Components, etc. SAM Associates offers a wide range of polyester sheets of different grades and specifications, with high precision thickness and durability.
