Therm-A-Gap 174, 274 & 574 Filler Pads

Therm-A-Gap 174, 274 & 574 Filler Pads

THERM-A-GAP™ 174, 274, and 574 represent the original gap-fillers from Chomerics. These materials have gained broad acceptance across multiple applications from everyday consumer products to the most rigorous applications in military and aerospace electronics.

 

These products are available with aluminum foil “A” or on “clean break” glass fiber “G”. As with all previous Chomerics gap-fillers, the “A” versions come with a high strength pressure sensitive acrylic adhesive for permanent attachment to the cold surfaces. The clean break “G’” versions have no adhesive, but are inherently tacky. In addition, 174 and 274 are available with “T” backing, which is composed of a rigid, acryli PSA-backed thermal insulation pad. This option provides a 0.25 mm (0.010 in) thick, tear and puncture resistant dielectric layer.
