Product Description

Honeywell's TGP8000HV is a Thermally Conductive Gap Pad which offers a good combination of low thermal impedance, high breakdown voltage and ease of use across multitude of applications. The naturally tacky property avoids the use of additional adhesive which could inhibit thermal performance.

Honeywell's TGP8000HV Thermal Gap Pads (TGP) have the lowest Thermal impedance out of all the entire thermal gap pad portfolio, plus higher breakdown voltage than the plain TGP8000 version. This and the hardness (30 vs 60 on shore00) are the main differentiating factors between the two. Their ultra-high compressibility enables low stress and excellent conformity to mating surfaces. They are designed to minimize thermal resistance at interfaces, and maintain excellent performance through reliability testing.

Honeywell's TGP8000HV ,in addition to High breakdown voltage, exhibits low oil bleeding and outgassing along with low hardness. The bleeding will depend on the pressure differential, the amount of uncross-linked silicone in the pad and the molecular weight of those unlinked chains. Available formats for TGP8000HV include standard sheets and custom die-cut parts that are available in a thickness range from 0.5mm to 5.0mm.

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.

Electrical Properties

Breakdown Voltage

Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that conducts electricity at some proportion of the total current.

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.

Volume Resistivity

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.

Dielectric Constant

Dielectric Constant
Dielectric Constant (k), commonly known as relative permittivity, is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current.

It determines the ability of an insulator to store electrical energy and is the ratio of electric permeability in vacuum against the electric permeability of a material.

The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field, making it a much better insulator.

It is a dimensionless property that can be affected by various factors such as the thickness uniformity of a material, insufficient contact between the sample and electrodes, water adsorption and contact resistance.

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.
