Rohacryl Foam

Acrylic-Based Foam Core for Composite Sandwich Design

Rohacryl is the newest material solution from Evonik's Performance Foams Product Line. Here another member of that product line: Rohacell PMI foam (© Evonik)

A new development in core material technology from Evonik Industries, Essen, Germany, has made its debut at JEC World 2018 in Paris. The newcomer to the Performance Foam family of products is Rohacryl - an acrylic chemistry based structural foam with high potential for composite applications.

Rohacryl foam is a core material solution that has excellent mechanical properties and is thermally stable. It is lightweight, easy to shape and environmentally friendly. Driving initial development of Rohacryl was the wind energy industry trend toward increasingly longer turbine blades that must meet demanding requirements. Ideally, materials used in blade production should be lightweight while providing both higher mechanical properties and an ability to remain stable when cured at high temperatures. According to Evonik, multiple material solutions in the market offered either high mechanical properties or withstood a high curing temperature, but not until the introduction of Rohacryl foam has a core material solution offered both in a single product. Other industries with similar efficient production methods may find the new product interesting for their applications.

The new foam product is the newest material solution from Performance Foams Product Line, a business that is already well-known worldwide for providing high performance Rohacell PMI foam. Its structural core material products have been used for more than 40 years in industries that include aerospace, automotive, electronics, medical technology, sports equipment and others.
