HGP14 | High Thermal Conductivity Gap Pad

Main features

0.10 Thermal Impedance
14 Thermal Conductivity
Low oil bleeding & Low volatile

Product Description

Honeywell HGP14 is a high-performance thermal interface material designed for efficient heat transfer in demanding electronic applications. It offers a thermal conductivity of 14.0 W/m·K, making it well-suited for systems requiring high thermal dissipation across varying bond line thicknesses.
The material is soft and conformable, allowing it to fill gaps between components and heat sinks without introducing significant mechanical stress. This makes it suitable for use with fragile components or assemblies where minimizing stress during installation is critical.

HGP14 also maintains material integrity over time, with low volatility and minimal oil bleed, reducing the risk of contamination or pump-out under thermal cycling. Its stability makes it a strong choice for applications sensitive to oil migration or where long-term performance is required.
Honeywell HGP14 is well-suited for high-power electronics, automotive systems, and telecommunications equipment, where superior heat dissipation and long-term stability are essential.

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

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.
