A powerful range of thermally conductive silicones from Momentive

Contact Us


A heat conducting material based on silicone has a very low surface tension and can therefore provide maximum contact surface with the hot part. Precisely the wetting property is decisive for obtaining a high total heat dissipation.

A powerful range of thermally conductive silicones from Momentive
Tribotec provides three types of technology for heat dissipation electronics: potting using an potting compound with high heat dissipation capacity, gluing of heat sinks with a thermally conductive adhesive, and grease as a heat transfer agent between heating element and heat sink.
A grease always remains uncured, and the part can be easily dismantled. Fat can also be made very heat conductive because you don't have to "get room" with the building blocks required to make an adhesive.

Silicone has many advantages

Silicones are substances with silicon as a base. Silicone comes in many different varieties and forms, such as oil, grease, rubber, liquids, resins and powders. Precisely the content of silicon gives the products a range of technical advantages that organic materials lack. Here we have compiled some of the strengths.

High temperature resistance
Of all types of adhesives, silicone generally provides 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, components around a car engine – all have to withstand high temperatures for a long time, and therefore silicone as an adhesive and protective material is the natural choice.

Resistant to UV radiation
Silicones are hardly affected at all by strong UV radiation, unlike most other types of glue. Products that are to be left outside (solar collectors, parts for space equipment, road signs, etc.) are therefore often glued and protected with these products.

Flexible in sub-zero temperatures
Silicone polymers and rubber retain their mechanical properties down to -60°C, some even lower.

Cooling systems, freezers, laboratory equipment, aircraft parts are typical applications where silicones are needed to cope with the low temperatures.

Resistant to water and moisture
Silicones are not broken down by water or moisture even over a long period of time and water absorption is minimal. Thus, the mechanical properties are maintained and the quality is assured for the entire life of the product. For underwater environments, outdoor environments and moist environments, these products are a safe choice of production material.

Resistant to chemicals
Silicones are generally a good choice as a sealant against chemicals. The selection of products is large. Consult with Tribotec about the right product for your application.

Food approved
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 above all FDA regulations.

Work environment friendly
Silicone is not classified as thermosetting plastic and most of the products are therefore very easy to work with in their production process. Thanks to this, a special adaptation of the workplace is generally avoided.
