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 ## SPECIFICATIONS |TYPICAL PROPERTIES|VALUE|TEST METHOD| |---|---|---| |Construction & Composition|Reinforced boron nitride filled|N/A| ||silicone sheet|| |Color|White|Visual| |Thickness Range|0.50mm (0.020”) 5.0mm (0.20”)|0.50mm (0.020”) 5.0mm (0.20”)
