RS PRO Gap Filler Material Thermal Pad, 4 W/m•K

RS PRO range of thermally conductive gap filler which due to their flexible design allows them to fill the air gap between uneven surfaces. Thermal gap pads provide a thermal interface between heatsinks (devices or substances for absorbing unwanted or excess heat) and electronic devices. They’re particularly useful where air gaps, rough surface textures or uneven surface topography prevent the use of traditional grease or paste.
Thermal gap pads are solid at room temperature, but as heat rises, they grow softer and can fill gaps. Often, devices are not entirely flush with the heatsink, and when the pad grows soft, it can spread and fill that gap.
RS PRO have a great range of products for the heating or cooling of electronic devices, components or enclosures to help devices maintain the right temperature to work effectively.

Options available with various thicknesses:
707-4679 - 0.5 mm
707-4673 - 1.0 mm
707-4682 - 1.5 mm
707-4685 - 2.0 mm
707-4689 - 3.0 mm


Very good thermal conductivity
Soft and high compressibilty
Natural tack
Easy to assemble
Good insulator

Typical Applications:

Electronic devices need to maintain the right temperature to work effectively. If the conditions become too hot or too cold, this can cause the components to malfunction. In order to keep electronics components functioning at the right temperature, the devices use a variety of different elements such as thermal pads that will keep the temperatures in the right parameters for quality performance. Thermal pads are used in various applications which include:
Electronic components
Flat panel displays
LED (light emitting diode) displays
Engine control units
Computer hard drives
Wireless communication hardware

How do thermal pads work?
By keeping the internal components of electronic products from wear and tear resulting from high circuit board temperatures, thermal pads help to provide extended longevity. They’re also important in providing safety by eliminating the possibility of electrical fires. Thermal pads are soft and comfortable, which helps to provide vibration and shock damping to minimise potential damage to components. They’re manufactured in a variety of standard thicknesses and dimensions but can also be custom fabricated to fit various applications.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards; they’re only given the RS PRO seal of approval if we’re confident of their exceptional quality, which means you can be confident too.
