Thermal Gap Filler

Thermal Gap Filler

Thermal gap fillers are a reliable heat transfer media which conform to surface gaps and irregularities to fill the air gaps and conduct heat from a heat source to another surface, or heat sink. Where space exists between two mating surfaces varies, whether from different shapes or rough surface textures, a thermal transfer concern is often present. Available in a wide variety of shapes, sizes, and thermal conductivities, thermal gap fillers are a cost-effective solution for some of the most difficult and delicate thermal situations in a broad range of applications.

(1) Where:

WWWW = Width in inches (ex 5.00″ = 0500

LLLL = Length in inches (ex 10.00″ = 1000)

TTT = Thickness in inches (ex 0.040″ = 040)

BD = Boron Nitride

S = Soft

SF = Silicone Free

(1) Options:

With adhesive: Add A to the end of the part number

With fiberglass: Add FG to the end of the part number

With Fiberglass and adhesive: Add FGA to the end of the part number

(3) Hardness is dependent on thickness
