Tputty 502 Series

Creates Compression Of Interface Material

Tputty 502 is the best material for applications where large tolerance differences create the need for compression of the interface material beyond 50% of its original thickness.

Tputty 502 will flow and ensure low pressures on the components being cooled. In conjunction with outstanding compression characteristics, Tputty 502 has a high thermal conductivity, resulting in very low thermal resistance.

Tputty 502 is naturally tacky and requires no additional adhesive coating that can inhibit thermal performance.

• Soft and ultra high compressibility for low stress applications

• 3 W/mK thermal conductivity

• Available in sheets 0.020” – 0.200” (0.5mm – (5.0mm) thick and in bulk

• Naturally tacky needing no further adhesive coating
