Separator Film

  • G-Flex EV100 – Meta-aramid coated film
  • G-Flex EV200 – Ceramic & Meta-aramid coated film
  • G-Flex EV300 – Ceramic & Para-aramid coated film

Battery Cell Solutions

The Gund Company provides flexible materials used in cylindrical, prismatic, and pouch cells of all sizes. These materials are designed according to our customers’ specifications to make the cell more efficient while also making it safer. The insulating properties of PolyPro FR and PolyPro EV make it an ideal solution for dielectric barriers within cylindrical cells and prismatic battery covings. G-Flex EV is a durable and low-density coated polyester with excellent wettability characteristics making it a great solution for separator films in all battery configurations.

Battery Pack Solutions

Electrical and thermal insulation materials are critical to ensure a battery system functions safely. The Gund Company manufactures electrical insulation materials to prevent arcing within the battery pack, and thermal insulation materials to inhibit heat transfer and combat thermal runaway.

Dielectric Barrier

  • Propellis – Flexible glass fabric with high-temperature epoxy
  • PolyPro FR – UL-49 V0 Polypropylene film
  • FR4 – UL-94 V0 Glass-Epoxy thermoset

We offer a variety of electrical insulation materials depending on the application need. Flexible materials such as PolyPro FR and Propellis are ideal for tight spaces that don’t require mechanical support such as linings and spacers. Other materials like FR4 exhibit similar dielectric properties while also providing mechanical strength. 

Thermal insulation materials such G-15 function similar to FR4 but in environments of much higher temperatures. Mica inhibits heat transfer which is critical to ensure heat generation is compounded within the pack. In instances where heat or flame has become uncontrolled, G-Flex FB functions as a flame barrier slowing the progression of a thermal event.
