Silicone-Free Interface Material Provides High Thermal Conductivity

MH&W International has introduced Keratherm U 90 thermal interface material for use where contamination concerns prohibit the use of silicone-based thermal pads, but where high levels of thermal conductivity are needed for sufficient thermal transfer in hot electronic devices.

U 90 material consists of a ceramic-filled polyurethane film with thermal conductivity of 6.0 W/mK and thermal impedance of just 0.05 Kin2/W. The material has a high voltage breakdown property of 4.0 kV. It provides strong perforation protection with a tensile strength of 2.5 N/mm2 and a Shore A hardness of 70.

   
Typical applications for silicone-free U 90 thermal interface pads include medical devices, laser equipment, lighting systems, solar energy, disc drives and aerospace electronics.
   
MH&W’s Keratherm U 90 interface material is available in 0.100 and 0.200 mm thicknesses.(3.9 and 7.8 mil). Standard and custom shapes are available in continuous rolls for automated or manual application. Pricing for U 90 thermal interface pads starts at $0.15 for 1 inch square, 0.200 mm thick pads in high volume quantities.
   
U 90 silicone-free thermal interface materials are part of the Keratherm line of thermally conductive interface materials. More information on U 90 pads can be found at www.mhw-thermal.com or by calling 1-201-891-8800 for samples and quotes.
