Thermal phase change materials on show

Electrolube is to demonstrate a range of capabilities and special products at this year’s Strategies in Light exhibition (Anaheim, California, February 28 - March 2). Marking its second appearance at this specialist LED lighting industry event, Electrolube will have technical specialists available to discuss issues that LED lighting manufacturers experience in the course of product development.

This includes  thermal management, environmental protection and colour shift problems associated with potting resins.

The new thermal phase change materials, TPM350 and TPM550, which offer high thermal conductivity levels of 3.50 and 5.50 W/m.K respectively. The low phase change temperatures encourage efficient wetting of the mating surfaces thereby ensuring minimal bond line thickness and reduced thermal resistance at the interface. Phase change materials provide an alternative to traditional thermal greases and both are silicone-free, have an operating temperature range of -40 to +125˚C and are RoHS-2 compliant. These products do contain small amounts of solvent to improve wettability on application, this rapidly evaporates following application to leave the solid phase change material on the substrate.
