ESSEN, GERMANY/ SHANGHAI, CHINA: Evonik’s ROHACELL PMI (Polymethacrylimide) rigid foam is helping aviation industry customers fly high through increased weight-reduction, fuel conservation, reduced emissions and excellent overall performance; evidenced by the material’s most recent use on the rear pressure bulkhead prototype of China's first large commercial airliner C919. It is the first time in China that a commercial aircraft applies composite material to its primary load-carrying structure.

Evonik played the role of a strategic partner during the design and development of the rear pressure bulkhead prototype for C919. ROHACELL material solution helps not only to realize the complicated spherical structure but also ensure its functions. Because of its outstanding material properties ROHACELL has proven to be excellent structural foam in fibre composite components for the aviation industry. The reduced weight saves fuel and also reduces carbon dioxide emissions.

“ROHACELL has already been successfully used in the winglet and flap vane of ARJ21-700, the Chinese own-designed regional passenger jet. With this new development on C919, we see our cooperation with the Chinese aerospace industry going on,” said Siamak Djafarian, General Manager, High Performance Polymers business, Asia Pacific, Evonik.
