A heat conduction material based on silicone has very low surface tension and can therefore provide maximum contact area with the hot part. It is precisely this wetting property that is crucial for achieving high overall heat dissipation.
A powerful range of thermally conductive silicones from Momentive
Tribotec provides three types of technology for heat dissipation electronics: moulding using a high heat dissipation moulding compound, bonding of heat sinks with a thermally conductive adhesive, and grease as a heat transfer medium between heating element and heat sink.
A grease always remains uncured, and you can easily disassemble the part. Grease can also be made highly thermally conductive because you don't need to "fit" the building blocks required to make an adhesive.

Silicone has many advantages
Silicones are substances with silicon as their base. Silicones come in many different varieties and forms, such as oil, grease, rubber, liquids, resins and powders. It is the silicon content that gives these products a number of technical advantages that organic materials lack. Here we have summarised some of the strengths.
High temperature resistance
Of all types of adhesives, silicone generally offers the highest resistance to temperatures above 150°C. Tribotec's range can withstand continuous heat around 200°C, and many variants even higher. Ovens, LED luminaires, car engine components - all have to withstand high temperatures for a long time, which is why silicone as an adhesive and protective material is the natural choice.
Withstands UV radiation
Silicones are hardly affected at all by strong UV radiation, unlike most other types of adhesives. Outdoor products (solar panels, aerospace equipment parts, road signs, etc.) are therefore often glued and protected with these products.
Flexible in low freezing temperatures
Silicone polymers and rubbers retain their mechanical properties down to -60°C, some even lower.
Refrigerators, freezers, laboratory equipment, aeroplane parts are typical applications where silicones are needed to cope with the low temperatures.
Resistant to water and moisture
Silicones are not degraded by water or moisture even over long periods of time and water absorption is minimal. Thus, mechanical properties are maintained and quality is assured for the life of the product. For underwater, outdoor and humid environments, these products are a safe choice of production material.
Resistant to chemicals
Silicones are generally a good choice as sealants against chemicals. The choice of products is large. Consult Tribotec for the right product for your application.
Food Authorised
Silicone is an inert material, and does not react with substances in its environment. Therefore, silicone-based products are well suited for food and medical technology. Tribotec has a large number of products approved according to FDA regulations in particular.
Labour friendly
Silicone is not classified as a thermoset plastic and most of the products are therefore very friendly to work with in their production process. Thanks to this, there is generally no need to make special adjustments to the workplace.
