Gap Filler Exhibits High Thermal Conductivity, Conformability

TP-S3LS ultra-low silicone gap fillers contain less than 50 parts per million of silicone while providing 3 W/mK of thermal conductivity between hot components and their heat sinks. Pads of the material are soft and compliant for easy compression and filling of air gaps between irregular mating surfaces. The material’s shore 00 hardness is 55 and it operates in temperatures up to 200°C. Additionally, the material has a UL 94 flame class rating of V-0 and its dielectric MH&W INTERNATIONAL CORP., Mahwah, NJ. (201) 891-8800.breakdown voltage is more than 5.0 kV. Pricing for standard flat sheets starts at $0.10 per square inch. For more information, call
