META-ARAMID PAPER WITH METASTAR 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℃.
- G-Flex™ YT511 is the uncalendared version of YT510, giving it a lower density and increased absorption characteristics. It has the same chemical composition and thermal performance as G-Flex™ YT510
- Flame Resistance: It is inherently flame resistant. It does not self-burn or melt in the room air, is non-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 is 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 papers from The Gund Company is a UL certified product: File # E521153
- Excellent Dielectric Breakdown strength
- Additional thicknesses are available upon request.
G-FLEX™ APA LAMINATES
Calendered and uncalendared papers and electrical grade polyester film bonded with the patented high-temperature adhesive technique are ordered. At high temperatures, these laminates will not delaminate or blister. The polyester film provides excellent dielectric strength, mechanical toughness, rip, tensile, and burst strength. Long-term thermal stability is achieved using Aramid paper and high-temperature adhesive. Applications for G-Flex™ APA include stator slot liners, phase insulations, coil wrap, conductor wrap, and other insulation applications for the electrical industry.
