NuSil Technology, a specialist in silicone materials for the healthcare and pharmaceutical industries, has introduced two thermally conductive healthcare silicone elastomers. These elastomers can be used as a cure-in-place adhesive or potting compound between electrical and electronic components and heat sinks as part of a thermal management regime to keep medical devices operating at optimal levels.    

MED-2980, a versatile 1.6 W/mK thermally conductive silicone, is available in a two-part configuration and is suitable for use with relatively large devices. MED-2955 is designed to have low volatility and low ionic content for sensitive electronic devices or processes. Both MED-2980 and MED-2955 are formulated to be used on a variety of substrates and to ensure contact between uneven surfaces. The two silicones are non-cytotoxic and can be cured at low temperatures or be heat accelerated. The low modulus characteristic of these elastomers ensures that, during operational thermal cycling, the bond line will not warp or break sensitive electronic components. The low volatility of MED-2955 makes it suitable for processing environments in which high heat or vacuum conditions require minimal contamination on adjacent parts. This material is also suitable for hermetically or near hermetically sealed environments in which low volatility is required. MED-2955 also provides a thin bond line and low thermal resistance with a bulk thermal conductivity of 0.63 W/mK.
