ROHACELL® WF has been designed for use primarily in aerospace applications; in addition to conforming to our material specification sheet, it satisfies the usual industry requirements such as MIL and CMS specifications.

Its outstanding properties make it an ideal material solution for aircraft components, including stringer structures in pressure bulkheads. This structural foam is also suitable for helicopter applications and is frequently used in the main and tail rotor blades, as well as fuselage panels.

ROHACELL® WF rigid foam can be processed at pressures of up to 0.7 MPa and temperatures of up to 130°C. It is therefore highly suited for autoclave prepreg processing and all typical resin infusion processes. After heat treatment, ROHACELL® WF can even tolerate curing temperatures of 180°C at a pressure of 0.7 MPa.

The minimal material properties are mentioned in the “Werkstoffleistungsblatt WL 5.1461” of DIN.
