...n a combustion engine. In cooperation with BASF, Wacker has developed Elastosil 76540 A/B adhesive to seal oil sumps made from Ultramid. In power supply systems for the medium- and high-voltage sectors, the very variably adjustable Powersil UV elastomers are popular. Another material, which may not at first be thought of as a plastic, is low-viscosity silicone oil, which serves as a cooling fluid in high-voltage transformers. These oils are replacing highly toxic halogenated transformer oils. Ha...

...future also take over in high voltage insulation: UV curing technology from Wacker Chemie AG, Munich, Germany. Unlike conventional silicone elastomers, that are thermally cross-linked, the crosslinking process in the UV silicones, marketed under the Powersil UV brand, is simply activated by irradiation with ultra-violet light. The cross-linking then continues by itself. The new technology has numerous advantages: Cross-linking of the UV silicones is rapid and can be flexibly adjusted to individu...

...cool the electric drive components is currently under discussion. Compared with the conventional water/glycol mixtures used to cool modern combustion engines, chemically stable, non-flammable silicone fluids, such as Powersil TR 50 which has long been used for cooling transformers, have the advantage of being electrically non-conducting. They also remain flowable down to -50 °C.Summary There is still a great deal of development and testing being done in the field of thermal management in electri...
