(polyester resin glass filament mat) General description: In cases where laminated paper is not strong enough but the top values of laminated glass fabric are not required, polyester resin laminated glass mat makes for an inexpensive alternative. This grade impresses users with its high mechanical strength and top electrical insulation. As well as complying with the most import ant standards, polyester resin laminated mats are suitable for further requirements. Due to the good electrical properties of this grade, it is used successfully in the electrical industry. Winding supports for dry transformers, partitions, switch levers in high-voltage switches, and insulators for choke coils – just some of the numerous poss ible uses. Characteristics and properties: - High dimensional stability
- Very good dielectric properties
- High temperature resistance, temperature limit of +155 °C as per VDE (Heat Insulation Class F)
- Self-extinguishing, meets the requirements of UL94 V-0 from 2.4 mm (type GPO-3)
- High track and arc resistance (type GPO-3)
