Silicone Cables with the Insulation & Sheathing Material Besilen®

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:

    • non-adhesive
    • hydrophobic

    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
    • ozone-proof
    • halogen-free
    • 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.

    Dielectric constant:   approx. 3,2 (bei 800 Hz)
    Specific volume resistance:  min. 1012Ω x cm
    Breakdown voltage:  20 kV/mm
