Automotive Flexibility, Opportunities, Innovations


Moulded seals, high-quality components as well as cable protection systems made from silicone and technical textiles

The typically used protection and insulation materials are characterised by their high temperature resistance and map the requirements and test catalogue of the leading OEM (LV312-3 ,...). Alongside the cable bundling itself, automotive electrics, also need, for example, heat protection of cable harnesses or the heat reflection in particularly hot areas of the vehicle. Of course, connection wires and cables must also be protected mechanically from damages. With various impregnation types and coatings, the braided or knitted sleeves are stabilised in their diameter and calibrated to the intended dimensions, with cut-proofing to ensure non fraying and water-proofing on the surface. Based on the special properties, silicone elastomers are particularly well suited as impregnation fluid or as rubber-like material for coating. Thanks to the excellent resistance to aggressive media and the wide range of usage temperatures silicone secures the flexibility and durability of the protective sleeves. The good electrical properties of the material also ensure excellent electrical insulation of cables and wires.

Textile reinforced silicone sleeves, moulded silicone seals and silicone profiles along with pure textile sleeves solve further application problems from the connector seal to the filling body in the generator of the airbag, the lighting technology, the flap and regulator seals and insulation through to the air conditioning in the vehicle.

BIW provides excellent handling of the interplay of the OEMs, the first tier, the ready-made items and the component suppliers in this segment. The development potential and competence of the company makes it a well respected partner for all automotive challenges and applications in which extremely high or extremely low temperatures are to be handled, high currents are to be insulated or simply protection and sealing functions to be implemented.

Particularly challenges are present when it comes to electromobility for which BIW develops and provides suitable insulation materials for motors and drives.
