Heat-Reflecting Flame-Retardant Silicone Foam Sheets
A thin layer of aluminized fiberglass on this silicone foam reflects heat to protect sensitive equipment. Foam, but not the adhesive, meets UL flame extinguishing specifications. Silicone maintains its flexibility across a wide range of temperatures. This foam has open-cell construction, which allows water, air, and gases to be absorbed. These sheets have an ultra-smooth texture for a sleek surface that's easy to wipe down.

T-Slotted Framing Caps, Covers, and Seals
Seal T-slots, rail ends, and gaps between rails to keep out dust, debris, and other contaminants.
Dust covers press into a T-slot to conceal wires and keep dust out. Aluminum dust covers are more durable than plastic covers. They give aluminum rails a finished look.

Flexible Electrical-Insulating Mica
- Color: Silver with Brown Spots
- Max. Temperature: 930° F
- Electrical Properties: Electrical Insulating
- Dielectric Strength: 508 V/mil
Also called muscovite mica, this mica is an excellent electrical insulator that resists temperatures up to 930° F. It's often used as wrap-around insulation for circuit breakers and heating elements. Meets UL 94 V-0 for flame retardance.
Ultra-Conductive Graphene Sheets
This highly conductive graphene material is often used in electronic devices, such as cell phones, laptop computers, digital cameras, and LEDs. It can be folded without tearing or damaging the sheet and can be cut into smaller pieces with scissors. Thickness, width, and length tolerances are not rated.
