Glass polyester is a laminate composite often used for electrical insulation. It’s available in multiple shapes, including rods, tubes and sheets, all of which come in a range of thicknesses and sizes. Glass-reinforced composite is made from cost-effective polyester and glass. Due to the polyester resin and the glass strand orientation, the material has outstanding track resistance, good mechanical strength, and low conductivity. Atlas Fibre has expertise with a wide range of thermoset composite materials. We can help you determine which material will best meet your project needs.
Glass-reinforced polyester, or thermoset polyester glass, is a type of material similar to phenolic composites. It’s made from fiberglass-reinforced polyester, which provides various mechanical and insulative benefits. Among the benefits of glass polyester are:
GPO-1, GPO-2, and GPO-3 are available in several shapes, including sheets, tubes, rods, and extruded profiles, such as channels, square tubes, and angles. Each shape has specific uses and benefits based on a project’s requirements. As your resource center, Atlas Fibre can help you select the right shape and size of glass polyester.
The applications for glass polyester depend on the type of material. rnrnGPO-1, the most economical option, is ideal for applications that require some degree of heat resistance but not flame resistance. It’s suitable for electrical insulating components, such as:
GPO-3 is the more advanced material. It offers superior arc, track and flame resistance to GPO-1 and GPO-2. It’s often the material of choice for transit applications and switchgear panels. It also performs well in High-voltage appliance insulation, Power distribution, Switchgear mounting panels and barriers.
If you need a thermoset composite material that is heat, flame and arc resistant, glass polyester may be right for you. We can help you choose the best material for your unique project needs. Contact us today for a quote.
