Particle foam for new lightweight components

Despite its low density the PESU particle foam thus enables extremely stiff and strong components with excellent dimensional stability at high temperatures. Expanded molded parts made from one single material offer numerous advantages compared to traditional honeycomb structures coated with phenolic resins: They offer considerable flexibility in terms of densities and shapes and therefore greater freedom in design. There are fewer processing steps and therefore lower system costs. Additional functional parts such as inserts and screw threads can be integrated in the complex geometries. And, last but not least, recycling of the parts can easily be carried out as the polymer is of one single origin. Thanks to such weight-optimized, thermoplastic foams for complex geometries it is possible to realize new lightweight components which, compared to traditional thermoplastic parts, have better properties and are an answer to trends such as e-mobility in automotive construction, the modernization of aircraft cabin interiors and increasing flame retardant requirements in public transport.
