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
- 7.8 W/(m K) Thermal Conductivity
- Non-Silicone Thermal Interface
- 90 Mil Wide-Gap Coverage
Product Description
Tflex SF890 is the 0.090 in (2.25 mm) grade in Laird's Tflex SF800 non-silicone gap-filler series. The grey, ceramic-filled sheet provides 7.8 W/(m K) thermal conductivity for silicone-sensitive thermal interfaces and is naturally tacky on both sides for placement without a separate adhesive layer. Shore 00 hardness of 81 and published pressure-based thermal-resistance data support design screening for installed interface behavior. The exact grade operates from -20 to 120 deg C and includes dielectric, volume-resistivity, and UL 94 V-0 data. Its preformed format supports controlled thickness across wider electronic gaps.
Key features
- 7.8 W/(m K) performance: Provides measured thermal conductivity for demanding interfaces.
- Non-silicone formulation: Supports thermal design in silicone-sensitive electronics.
- 90 mil wide-gap pad: Nominal 0.090 in thickness bridges larger interface gaps.
Applications
Automotive ADAS; Automotive Electronics; Automotive Infotainment; Automotive Powertrain/ECUs; Drones/Satellites; Gaming Systems; Instrumentation; Notebooks/Tablets/Portable Devices; Routers; Smart Home Devices; Solid State Drives; Wireless infrastructure
