0.5 - 5 mm Thickness

Product Description

Honeywell TGP 3500PT Thermally Conductive Putty Pads provide high thermal performance and excellent thermal reliability. The material’s putty-like design enables excellent gap-filling capability for applications with large dimensional variances. Special surface reinforcement enables easier handling for operators during high volume assembly. It comes packaged with single (>=1mm) or double (<1mm) sided fiber glass and dual liners.

Honeywell TGP 3500PT is naturally tacky and requires no additional adhesive to mate to heat source and heat sink. This product can improve production efficiency by replacing pre cured gels and is available in thicknesses ranging from 1.0mm to 5.0mm.

Need a thickness below 1mm? Then we recommend our standard Thermal gap pads.

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.

Mechanical Properties

Hardness Hardness Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.

Electrical Properties

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.

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.

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.
