Thermal Management

Thermal insulation is achieved by materials that retard or slow the transfer of heat from one surface to another. Thermal blocking is required for a variety of processes, and Fralock offers effective and durable solutions using specialty polyimide materials and silicone foams that are available in various custom shapes and sizes, and thicknesses. DuPont™ Cirlex®, manufactured by Fralock, creates a highly effective thermal break between two surfaces.

Thermal Spreaders – We offer effective thermal spreaders to assure uniform heat dispersion across an entire surface (with TC-XY surface >200 W/m∙K). An example is Fralock Thermal Spreader AS, which functions as a gap filler and thermal spreader, and reduces thermal resistance, eliminating heat retention. Similar function materials include graphite, metal foils, and thermally-conductive gap fillers.

Gap Fillers – Thermal gap fillers are thermally conductive materials that eliminate air gaps between interfacing components and enhance efficiency of heat transfer. Fralock offers high thermally-conductive silicone rubber gap fillers (with TC-Z surface as high as 17 W/m∙K) as thin as 0.3mm. We can assist in selection and precision manufacturing of complex thermal management fillers with very high thermal conductivity in the thru-plane, providing excellent heat transfer.
