Tputty ™ 502

Tputty ™ 502

Silicone based Thermal Gap Filler

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.


Tputty 502 is available in bulk form in the following sizes: 100 cc Jar 500 cc Jar 1000 cc Jar

Consult the factory for alternate bulk sizes.

Standard Sheet Sizes

9 x 9 (229mm x 229mm) and 18 x 18 (457mm x 457mm).

9 x 9 only over 0.100 thickness

Tputty 502 is available in individual die cut shapes. Pressure sensitive adhesive is not applicable for Tputty products.


Tputty 502 sheets are reinforced on both sides with fiberglass.
