Engineering plastics, also called construction plastics, can be used for the most demanding applications in terms of mechanical strength, heat resistance and resistance to chemical attack. In the so-called plastics pyramid, they are therefore higher than standard plastics such as PE, PE and PVC, but still below the high-performance plastics. In many cases, engineering plastics are an excellent alternative to metals, glass or even ceramics. With function-integrated design and construction as well as sophisticated production methods, customized compounds can be used for realizing high-quality and cost-efficient components. They therefore offer a unique potential for innovation in a wide variety of applications such as automotive and industrial, renewable energy, medical technology and transport. Compounding with its specific possibilities is often the key to achieving the necessary material properties.
