Products
Thermoset
Protek Frac Balls are made to outperform competing products in the most demanding conditions. Whether you need greater performance for fracing, or in your sleeve or casing applications, these are emerging leaders in the market. The E5 Frac Balls from Protek are now available from The Gund Company.
Standoff Insulators are made of a polymeric composite material that has received UL recognition. A manufacturing environment compliant with ISO 9001:2015 regulates the production process. Each lot is mechanically and electrically tested to ensure performance and dependability for the most demanding electrical applications.
Ranprex® densified laminated wood insulation for electromechanical applications is extensively used in the liquid filled power and distribution transformer industry. The material complies with the norms DIN7707 & IEC61061, and typical applications for components
Thermoplastic

5G application potential spans far beyond cellular network support. 5G opens the door to smart cities, IoT, and V2V technology.
Still, lower latency communications and higher data storage potential are necessary to match this new technology. A more significant number of base stations utilizing steerable, high-frequency, and high-efficiency antennas are required to support these applications.
Flexibles
The Gund Company's brand of flexible insulation products, including aramid paper, flexible laminates, wire sleeving, felts, cordage, surge ropes, and insulating tapes. Used in various electrical applications in the following markets: Motors, Generators, Transformers, Electronics, and Switchgear.
Manufactured in the United States, PolyPro FR® is a UL-Listed V0 flame retardant polypropylene extruded for high and low-voltage electrical insulation applications. PolyPro FR® can be converted using traditional converting techniques and thermoformed to match complex shapes.
The Gund Company’s aerospace manufacturing process results in the production of high-quality slot armor. Rotoguard® is the most uniform and consistent slot insulation commercially available today. The result is a series of high-quality generator insulation products that save installation and schedule time and help prevent premature failure.
G-Flex™ APA laminates can be used as slot, phase, end turn insulation, ground, and wrapper insulation in dry-type transformers, generators, and various punched and fabricated parts. These laminates can be employed in hermetic applications since they have minimal volatiles. Standard 36-inch-wide rolls on 3-inch diameter cores are ordered. Requests for slit-width rolls, cut sheets, unusual core sizes, and non-standard lengths may be possible.
Resistance Temperature Detectors (RTDS)
The RTD can be embedded in either NEMA G-11 or The Gund Company’s Semi-Conductive materials up to 109 inches for installation into the stator of your application. NEMA G-11 provides mechanical protection for the RTD during the installation phase and protects the RTD throughout its life span. The Semi-Conductive material provides the same mechanical protection with the added benefit of corona dissipation.
