MH&W International has added new TP-S3LS ultra-low silicone
gap fillers to its line of thermal interface materials.
TP-S3LS pads contain less than 50 parts per million of
silicone while providing 3.0 W/mK of themal conductivity
between hot components and their heat sinks.

The gap filler's minimal silicone content makes it suitable for use
in silicone-sensitive applications including medical
electronics, laser optics and telecommunications where
silicone-based outgassing can lead to contamination and
condensation issues or leave oily residues that interfere
with process applications.

The TP-S3 family of materials was developed by Chang Sung Corp. and is manufactured by
Dongyun Electronics in South Korea.

Pads of TP-S3LS material are soft and compliant for easy
compression and filling of air gaps between between
irregular mating surfaces. The material's Shore 00 hardness
is 55. TP-S3LS pads can be used in temperatures up to
200°C, which exceeds the use range of silicone-free gap
fillers. The material has a UL 94 flame class rating of
V-0. Its dielectric breakdown voltage is more than 5.0 kV.

New TP-S3LS gap filler material is available in 210 x 297
mm (8.3 in x 11.7 in) sheets or die-cut parts. Standard
sheet thicknesses range from 0.5 to 5.0 mm (0.020 in to
0.196 in). An optional fiberglass liner is available on 0.5
mm (0.020 in) thick pads where added handling strength is

Pricing for standard flat TP-S3LS sheets starts at $0.10
per square inch, which is below the cost of other 3.0 W/mK
thermal gap fillers now available. Lower priced TP-S3 gap
fillers are also available with thermal conductivities of
2.0 and 1.0 W/mK.
