LAIRD TFLEX HD380
Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg
Main features
- 80-Mil Variable-Gap Coverage
- Low-Resistance Surface Wetting
- Low-Stress Board Interface
Product Description
Tflex HD380 provides the Tflex HD300 high-deflection gap-filler material in a nominal 0.080 in sheet. The pink ceramic-filled silicone construction offers 2.7 W/(m K) thermal conductivity and conforms across manufacturing tolerances with low pressure-versus-deflection behavior. Strong surface wetting reduces contact resistance while the compliant pad limits mechanical loading on boards and components. Typical family properties include 3.1 g/cm^3 density, Shore 00 hardness of 38, and a -40 to 200 deg C temperature range. The 80 mil grade fits thermal-management assemblies in automotive electronics, gaming systems, instrumentation, portable devices, routers, and wireless infrastructure.
Key features
- 80 mil thickness: Provides the Tflex HD300 material at a nominal 0.080 in.
- High-deflection interface: Fills manufacturing-tolerance gaps with low mechanical loading.
- Low contact resistance: Surface wetting complements 2.7 W/(m K) thermal conductivity.
Applications
Automotive ADAS; automotive electronics; automotive infotainment; automotive powertrain/ECUs; drones and satellites; gaming systems; instrumentation; notebooks, tablets, and portable devices; routers; smart-home devices; wireless infrastructure.
