Composite Fiber Aramid Honeycomb Panels

Fiberglass Face

With an aramid honeycomb core sandwiched between carbon fiber or fiberglass for rigidity, these panels are strong, but lightweight, and won’t conduct heat. Often used as wall panels in structural and insulating applications, they’re a lightweight alternative to solid composite and aluminum honeycomb panels.

Fiberglass Face—Fiberglass-faced panels are often used around electrical components because they are good electrical insulators. They resist cracks from bumps and hits better than carbon-fiber-faced panels, but are not as strong or lightweight.

High-Temperature Electrically Insulating Tube Wire Sleeving

This sleeving is often used to insulate connections in transformers, relays, and solenoids. It prevents electricity and heat from dissipating from wire and cable. When exposed to flame, it will self-extinguish and produce a nonconductive ash. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Made of silicone-coated fiberglass, it resists chemicals.

Expandable Electrically Insulating Tube Wire Sleeving

A specially formulated silicone rubber coating allows this fiberglass sleeving to stretch over items during installation; it then tightens around its contents for a secure fit. Often used in motors, generators, and transformers, it prevents electricity and heat from dissipating from wire and cable. It has good chemical resistance.
