HLT 3500LV | Two part Hybrid Thermal Gel
- Blue + White
- 3.5 Thermal Conductivity
- 0.44 Thermal impedance
Product Description
Honeywell HLT3500LV is a two-part, dispensable thermally conductive gel, which offers long-term reliability and superior softness. The enhanced bonding force between the polymer base and the filler largely improves the thermally conductive gel oil separation issue in storage. Prior to curing, the material maintains good thixotropic characteristics and low viscosity to be easily dispensed. The product can be cured in short time after two- component mixing at room temperature. The high compressibility minimizes thermal resistance at interfaces, while maintaining excellent performance during reliability testing. It is the Low Volatiles version of HLT 3500 with less than 50ppm on Σ D3-D20.
Honeywell HLT3500LV is a balanced solution for Vertical mounting that requires high TC before we go into the upper end of the product line. The enhanced bonding force between the polymer base and the filler largely improves the thermally conductive gel oil separation issue in storage. Prior to curing, the material maintains good thixotropic characteristics and low viscosity to be easily dispensed.
Cure Schedule
- 18 hours at Room temperature or
- 30minutes at 100°C.
These are just indications. You can experiment with curing for your application needs.

Specific Gravity 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. | 3.1 | ||||

Viscosity 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 water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application | 200,000 - 400,000 mPa.s | ||||

Thermal Conductivity 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. | 3.5 W/m.K | ||||
