Rohacell WF Performance Foams

ROHACELL WF foam core has been specifically designed for use in aerospace applications. Based on polymethacrylimide (PMI) chemistry, it is engineered to meet demanding requirements from aircraft manufacturers and has led to many specifications for more than 30 years, including MIL, CMS and others.

Rohacell WF

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.
