LAIRD TFLEX 370TG
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
- Cut-Through-Resistant Tgard Barrier
- Mass-Production Part Handling
- Compliant 1.75 mm Gap Filling
Product Description
Tflex 370TG combines a 1.75 mm filled silicone thermal gap-filler sheet with a Tgard carrier liner. The reinforced construction supplies a cut-through-resistant dielectric barrier while improving part handling for mass production. Typical thermal conductivity is 1.2 W/(m K), Shore 00 hardness is 27 and nominal thickness tolerance is +/-10%. Low compression set permits repeated pad use, and the light-green material operates across -40 to 160 deg C. The sheet is adhesive on one side for placement.
Key features
- Tgard dielectric barrier: Adds cut-through resistance to the reinforced sheet.
- 1.75 mm grade thickness: Provides a preformed interface with +/-10% thickness tolerance.
- Production handling: The carrier liner supports easier part handling in mass production.
Applications
Applications include telecom hardware, flat panels, memory modules, power conversion, automotive electronics, LED lighting and handheld electronics.
