Performance Foams

Performance foams are exactly what your application needs! Whether you choose ROHACELL® or ROHACRYL^TM, we have the perfect high-performance, lightweight foam core solution to meet your processing parameters and application performance requirements.

Many markets benefit from Perfomance Foams

Lightweight construction is in great demand for a broad range of applications. It therefore comes as no surprise that performance foams are used in countless areas. However, low weight is just one of many advantages the materials have to offer.

Aerospace and Aviation

New designs are increasingly replacing conventional metal structures with lightweight, high-performance fiber composites. Our performance foam core materials for sandwich-design composites can satisfy the needs of both exterior and interior applications.

Sports & Lifestyle

Sandwiched designs with cover layers made of fiber plastic composites such as CFRP and core materials such as ROHACELL® are the trend in high performance sports equipment.

High Performance Foams for All Your Applications and Processes

Whether your selection criteria include density, processing temperature, cell size or a specific mechanical property performance level, we offer a full line of structural foam products to meet whatever your project requires.

ROHACELL®

ROHACELL® foam has been a core solution in sandwich design composite applications since 1972 and provides impressive mechanical strength, even at very low densities, with a heat distortion temperature and creep compression strength superior to any other rigid foam. For select grades, properties can be even further enhanced with heat treatment.

ROHACRYL™

ROHACRYL™ has been developed to meet the requirements of high-volume industries with a clear focus on lightweight and sustainable applications. Its high performance and contribution to sustainability are a step ahead for products, processes and value chains in the composite industry.
