During use, some electronic components can generate significant amounts of heat. Failure to effectively dissipate this heat away from the component and the device can lead to reliability concerns and reduced operational lifetimes. Electrolube’s extensive Thermal Interface Material (TIM) Range is designed to help reduce the operating temperature of many different electronic devices. With any thermal application we would always advise testing before final selection as the requirements and operating environment will vary for each application.

Newton’s law of cooling states that the rate of loss of heat is proportional to the temperature difference between the body and its surroundings. Therefore, as the temperature of the component increases and reaches its equilibrium temperature, the rate of heat loss per second will equate to the heat produced per second within the component. This temperature may be high enough to significantly shorten the life of the component or even cause the device to fail. It is in such cases that thermal management measures need to be taken. The same considerations can be applied to a complete circuit or device which incorporates heat producing individual components.

Heat is lost from a component to its surroundings at the surface of the component. The rate of loss of heat will increase with the surface area of the component; a small device producing 10 watts will reach a higher temperature than a similar powered device with a larger surface area.

This is where heat sinks are used – varying in size and shape, heat sinks can be designed to offer a significantly increased surface area to maximise heat dissipation. They are typically connected to components which generate a large amount of thermal energy when used and therefore dissipate such energy away from the device to avoid failure due to over-heating.

Heat sinks have proven to be very effective over the years however in order to ensure full contact and therefore maximum efficiency, thermal management products are used alongside.

Metal surfaces, even when polished to a fine degree, have a certain amount of roughness. It can therefore be deduced that when two metal surfaces are placed together contact is not 100% and there will always be an air gap between the two surfaces. The use of a thermal interface material between such gaps ensures complete contact between the two surfaces and in turn more efficient heat conductance.

The ongoing trend for product miniaturisation – coupled with more modern, higher powered devices – has ensured that efficient thermal management is an essential part of both modern and future electronics design, the LED lighting market being just one example. Thermal management products are also offering solutions for greater efficiency in green energy development; photovoltaic inverters – which are known to be particularly sensitive to temperature; connections between the heat-pipe and water storage tank for solar-heating applications; hydrogen fuel cells; wind power generators, are just a few examples.

ER2222  - Red Thermally Conductive Epoxy

ER2222
Red Thermally Conductive Epoxy

5kg - 25kg

Product code: ER2222K5K - ER2222K25K


ER2222 is a red variation of Electrolube's ER2221 Thermally conductive Epoxy potting compound. The resins properties are identical to ER2221 but has been formulated with a red finish for aesthetic appearance.

It's a highly temperature resistant epoxy with excellent thermal conductivity and a wide operating temperature range -40°C to +150°C retaining excellent characteristics even through extensive thermal cycling.

Although ER2222 is a filled system, it is easy to mix and has a low viscosity allowing the resin to flow around and under tricky components or into tight spaces.

ER2222 are an excellent choice for encapsulating an electronic device which requires high levels of thermal resistance and protection such as automotive, aerospace, industrial or other applications which are subject to harsh environments.


Key Properties:
  • Two component red epoxy resin
  • Excellent high temperature resistance up to 150°C
  • Enhanced thermal conductivity
  • Low viscosity for a filled system;
  • Does not contain abrasive fillers; low wear on dispensing machinery
  • Meets UL94 V-0
  • RoHS Compliant
