Thermal management systems made from a recently introduced injection moulding–grade thermoplastic can weigh 50% less than metal-based parts.
Parts made from the thermoplastic can weigh 50% less than their aluminium counterparts, and the material provides engineers with a broad palette of design options, according to the company. The polymer will not amplify electromagnetic or radio-frequency interference or magnetic coupling.
Two grades are currently available. CoolPoly’s E-series grade is electrically conductive and provides inherent EMI and RFI absorption, while the D-series formulation is electrically insulative and produces no signal interference or magnetic coupling. Polymer specifications include 20 W/mK thermal conductivity, 0.1 cm2/sec thermal diffusivity, and 1.7 g/cm3 density.
Cool Polymers can supply compounds for injection moulding, off-the-shelf moulded parts, or parts moulded to customer specifications. Samples are available on request.
