TFLEX UT20000
Tflex UT20000 Series
Ultra-thin gap filler offering great thermal performance and handling
Tflex™ UT20000 is a specially formulated ultra-thin gap filler thermal interface material designed for thin interfaces that offers excellent thermal performance and high compliancy. It is designed without embedded reinforcing fiberglass to minimize contact resistance, yet still allows easy material handling and durability during assembly.
The elastomeric property of Tflex™ UT20000 provides excellent interfacing and wetting out mating surfaces in thin interface where efficiently transfer heat away from components. It is an ideal choice for low-pressure applications and optimum solution in handheld devices with thin interface gap and limited space requirements.
Tflex™ UT20000 is electrically non-conductive, stable from -40°C thru 200°C and offered in thicknesses that range from 0.008” (0.2mm) up to 0.040” (1.0mm).
