Meta-Aramid Paper with Metastar

G-Flex™ YT510 meta-aramid paper is manufactured from 100% aramid fibers. It carries a Temperature Index (TI) of 210°C, a VTM-O Flame Rating, and full UL approval (File #: E521153). This paper offers high inherent dielectric strength, mechanical toughness, flexibility, and resilience. Applications for G-Flex™ include stator slot liners, phase insulations, coil wrap, conductor wrap, and other insulation applications for the electrical industry.
G-Flex™ Meta-Aramid Paper Benefits
- Heat Resistance: G-Flex™ YT510 meta-aramid paper has long-lasting thermal stability. It can be used for many hours at high temperatures while maintaining excellent dimensional stability. It will not embrittle, soften or melt when it is exposed temporarily at high temperatures of 300℃.
- Flame Resistance: It is inherently flame resistant. It does not self burn or melt in the room air, no combustion-supporting, and has the property of self- extinguishing.
- Electrical Insulation: The meta-aramid fiber has very good electrical insulation properties. The dielectric strength of meta-aramid paper more than 20kv/mm.
- Chemical Stability: Meta-aramid fiber has a very stable chemical structure. It is resistant to most strong inorganic acid and to alkalis at room temperature.
- Recognized by Underwriters Laboratories (UL) as a 210°C insulation.
- Sold directly from The Gund Company and readily available in 7 locations in 4 countries.
- G-Flex™ meta-aramid paper from The Gund Company is a UL certified product: File # E521153
- Excellent Dielectric Breakdown strength
- Additional thicknesses are available upon request.
