Engineering foam made from high-performance plastics

  For lightweight applications in aerospace, electronics, medical & industry  

Conventional foam products, such as EPP and EPS foams, often struggle to meet increasing performance demands. High temperatures, mechanical endurance or chemical resistance are difficult to achieve cost-effectively with traditional materials.

Ensinger now offers a future-oriented solution in the form of our engineering foam, which is based on high-performance plastics such as PEEK, PESU and PC. It is the ideal choice for demanding applications and complex functionality. The combination of engineering polymers and unique foam properties results in high performance foams that are lightweight yet robust, and resistant to impact, heat and chemicals.
In addition, our innovative, energy-efficient production process enables us to create finer cell structures and customisable densities. This allows us to create an engineering foam that can be precisely adapted to meet specific customer requirements.
