## Tputty[TM] 502 Series Thermal Gap Filler 

## PRODUCT DESCRIPTION 

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

Tputty™ 502 will 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. 

## FEATURES AND BENEFITS 

- 3 W/mK thermal conductivity 

- Soft and ultra high compressibility for low stress applications 

- Fiberglass layer for reinforcement and better handling capabilities 

- Low Dielectric Constant 

- Environmentally friendly solution that meets regulatory requirements including RoHS and REACH
