TG 5500 | Thermal Grease
- 0.01 Thermal Impedance
- 5.5 Thermal Conductivity
- 23μm BLT
TG5500 Thermal Silicone Grease offers the highest thermal conductivity of our product line (5.5 W/mK) and a controlled bond line thickness of 23 micron @35psi, 50oC. Its viscosity and excellent thixotropy make it fit for large–scale production with dispensing, screen printing and stencil printing. It is an excellent, option for thermally demanding applications that can support a >20um BLT.
TG5500 is used for applications with high power density requirements. It provides superior thermal performance with ease of use across a multitude of applications. It is a stable homogeneous mixture under room temperature with an operating temperature range of -40oC to 150oC. Please note that this thermal grease contains solvent and requires a drying step.

| Specific Gravity |
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
| Viscosity |
Viscosity is a measurement of a fluid’s resistance to flow.
Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.
A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application
| Volume Resistivity |
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
| Thermal Conductivity |
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.
Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.

UL 94 Rating
Flammability rating classification.
It determines how fast a material burns or extinguishes once it is ignited.
HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm
V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole
