Description

Universal Science™ UniPhase™ 7500 is high-performance phase change Material TIM that has non-silicone formulation that provides naturally tacky surface, with a thermal conductivity of 7.5 W/Mk, it is also a great replacement for messy thermal grease applications.

This thermal interface material has enhanced the cooling of the most Demanding thermal applications. Phase change occurring at 60°C +/- 10°C. In combination with device mounting pressure and phase change flow, expels air voids at the interface helping to reduce thermal resistance on top of having long term reliability and no pump out.

This material is supplied in die-cut preforms to suit a wide variety of electronic applications such as DC/DC power converters and is typically between any heat dissipating electrically isolated component and heatsink.

This material is supplied in thicknesses of 0.125mm – 0.4mm
