TFLEX HR400

MID-PERFORMANCE GAP FILLER WITH 1.8 W/MK

Tflex HR400 is a cost-effective and compliant gap filler thermal interface material with excellent thermal performance and great handling for mass-production applications.

The low modulus interface pad conforms to component topography resulting in little stress on the components mating chassis or parts. The softness relieves mechanical stress from high stack-up tolerance and absorbs shock resulting in improved device reliability.

Tflex HR400’s recovery properties for applications requiring material rework result in continued mechanical integrity even after device rework and re-assembly. Tflex HR400 is naturally tacky on both sides and requires no additional adhesive coating to inhibit thermal performance. The tack is designed to hold the pad in place during assembly and component transport.

Tflex HR400 is electrically insulating stable from -50?C thru 160?C and meets UL 94V0 flame rating.

• Thermal Conductivity 1.8 W/mK

• Soft and Compliant

• Available in thicknesses from 0.020” thru 0.400” (0.5mm thru 10.2mm)

• Naturally tacky for adhesion during assembly and transport

Additional Product Description STANDARD THICKNESSES
Standard thickness is 0.020-inch (0.5 mm) through 0.400-inch (10.2 mm) and available in 0.010-inch increments. Please contact Laird Technologies for availability of thicknesses above 0.200-inch.
OPTIONS
Fiberglass is standard in 0.020-inch and 0.030-inch thicknesses to aid in handling and is designated by the suffix “-FG”. Material is standard with both sides tacky; the -DC1 suffix indicates only one side is tacky.
