Tflex HR600

Silicone based Thermal Gap Filler

Product Description

Mid-Performance Gap Filler with 3 W/mKTflex HR600 is a cost-effective and compliant gap filler thermal interface material withexcellent thermal performance and great handling for mass-production applications. The low modulus interface pad conforms to component topography, resulting in little stresson the components, mating chassis or parts. The softness relieves mechanical stress fromhigh stack-up tolerance and absorbs shock, resulting in improved device reliability. TflexHR600s recovery properties for applications requiring material rework result in continuedmechanical integrity even after device rework and re-assembly. Tflex HR600 is naturally tacky on both sides and requires no additional adhesive coating toinhibit thermal performance. The tack is designed to hold the pad in place duringassembly and component transport. Tflex HR600 is electrically insulating, stable from -45ºC thru 200ºC, and meets UL 94V0flame rating. Standard Thicknesses 0.010-inch to 0.200-inch (0.25 to 5.0 mm) 0.010-inch and 0.015-inch thick materials come standard with fiberglass reinforcement designated by the suffix œFG Options Proprietary DC1 option available to eliminate tack from one side to aid in handling.
