Besilen® - Elastomere on a silicone caoutchouc base
Besilen® is a registered trademark of SAB Bröckskes GmbH & Co KG. It is a specially developed Silicone rubber-based material with good electrical characteristics and heat resistance. In addition to our standard Besilen® product range, we also produce specialised products that meet requirements such as:
Types of Silicone Cables:
- notch resistance for better mechanical strength
- hígher temperature resistance + 250 °C
- Besilen® - mixture compatible for the food industry
- conductive Besilen® for antistatic conductance
Mechanical characteristics of silicon cables
Vulcanised Besilen®, produced with a 50-60 A shore hardness is particularly elastic with excellent mechanical strength. A further interesting characteristic of Besilen® is that it does not stick to adhesive surfaces.
Silicone cables are:
If Besilen® cables are used in tube systems it is important that these are ventilated and open, otherwise the mechanical strength of Besilen® will be reduced.
Chemical characteristics of silicone cables
The chemical composition of Besilen®, which deviates from standard rubber types, gives our product several outstanding characteristics including for example:
- outstanding hot air resistance
- extreme flexibility at low temperatures (down to -40°C)
- resistant to decompostion from substances such as alcohol and high molecular oils, plant and animal fats, dilutes acids, softeners, chlophen, alkalis and salt solutions
- oxygen resistant
- weather resistant
Electrical characteristics of silicone cables
The electrical characteristics of Besilen® even at room temperature lie alongside the best known elastic insulation materials. Because of its heat resistance, Besilen® insulated cables and wires can withstand approx. 50% more electric pressure under continuous use than regular rubber insulation. This allows weight and room-saving cable construction. An outstanding safety feature of Besilen® insulation is the insulating layer of silicic acid (SiO2) during fire.
