With a thermal\n      conductivity of 2.0 W\/m·K, it is designed to\n      fill gaps and uneven interfaces between\n      heat-generating electronic components and heat\n      sinks. The material remains soft over time\n      and provides electrical insulation, water\n      resistance, low oil separation and low volatility.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!--
