Power Electronic Applications

The Gund Company manufactures and fabricates a broad range of materials that can insulate the most demanding power electronics applications. Composite materials serve as heat shields, dielectric barriers, air baffles, and electrical insulation in transformers. Many flexible thermoplastics serve as board liners, battery insulation, and capacitor shields. Also, composite electrostatic dissipative (ESD) materials help combat the destructive nature of corona discharge in electronic manufacturing environments. The Gund Company manufactures custom solutions for a wide range of applications in the following types of equipment:

The Gund Company also offers a wide variety of elastomeric materials available for all your enclosure sealing, O-ring, thermal shielding and gasket needs.

PolyPro FR®

PolyPro FR® II is a flame retardant polypropylene that carries a UL 94 V-0 flame class rating with features that make it an economical choice for electrical insulation applications. The material is available in a range of standard thicknesses from 0.010” to 0.125”. PolyPro FR® II can be fabricated into a wide range of designs using cost effective fabrication methods such as die cutting or knife cutting. It also exhibits excellent formability characteristics allowing it to be scored, shipped flat, and quickly folded into many three-dimensional shapes. PolyPro FR® II provides a lower cost alternative for designs incorporating the use of materials such as aramid papers or polycarbonate films.
