Fujipoly Thermal Interface Materials

Fujipoly Thermal Interface Materials

Fujipoly SARCON® is a family of thermal interface materials (TIMs) made from a thermally-conductive silicone and is highly flame-retardant. SARCON® is available as thermal putty, gap filler pad, thin film, grease, and dispense-in-place products.

Insul-Fab is proud to be a Fujipoly Authorized Distributor and Converter of custom SARCON thermal interface materials, fabricated under a rigorous AS9100-certified quality system, with short lead times, competitive pricing, and low minimums. Many Fujipoly products offer superior thermal management and high value when compared with similar materials from other well-known manufacturers.
