The electronics industry requires plastics with precisely defined properties. Siemens is developing technologies that make it possible to combine materials in such a way as to meet increasingly specific demands. Each of us is in contact with plastics every day. In toothbrushes, ballpoint pens, smartphones — there’s no getting away from plastic, or, as the experts put it, synthetic polymers. Many of these everyday plastics have straightforward properties such as light weight, flexibility or hardness. Plastics for use in industry, especially in electrical engineering, require much more specialized properties. These range from transparency and magnetic qualities to the ability to withstand temperature extremes, and the ability to conduct – or minimize conduction of – heat or electricity.
