ROHACELL® polymethacrylimide (PMI) closed cell foam cores provide all the stiffness, robustness and durability required in composite structures at a fraction of the weight of other core products. Specifically designed to meet the demands of the wind energy industry, ROHACELL® WIND-F is compatible with all common epoxy and polyester resin systems and delivers excellent mechanical properties at low foam densities while sustaining continuous process temperatures up to 150 °C. Lightweight ROHACELL® WIND-F is available in nominal densities as low as 50 kg/m³. Even at these low densities, the GL requirements for core materials can be met.Information provided by Evonik |
