Product Description

HT3500 silicone based one-part Gap Filler - thermal gel provides a thermal conductivity of 3.5 W/mK along with high conformability and high compressibility. It is formulated to deliver high dispense rates for improved productivity, long-term reliability performance and easy reworkability.

HT3500 is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost. The minimum bondline thickness that it can reach is 0.1mm with a Thermal Impedance of 0.4. Additionally it performs great in oil,crack and slump testing and it exhibits no pump out and cracking risk. This is the most popular, commercial version of the material but we also provide the LV (low volatile) version for specific applications such as optical that might require i.e less clouding.

HT3500 has a high flow rate, above 15 g/min, high breakdown strength (above 5 kV/mm) and very low out gassing (below 0.5%)

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.
Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 25°C 365 days
Thermal Properties
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.
