Product Information

ROHACELL® IG-FROHACELL® IG-F structural foam is a closed-cellrigid foam based on polymethacrylimide (PMI)chemistry and contains no CFC's.
The “IG” in ROHACELL® IG-F stands for “Industrialgrade.” It is the standard product in our range ofrigid foam products and is suitable for a wide
variety of automotive, medical and industrial
applications.
The “F” in ROHACELL® IG-F indicates the foam’s
fine cell structure that will take up only minimalresin at the surface where the cells have been cut
open. Less resin take-up during part processingmeans less final part weight and overall cost.

PROCESSING AND PRODUCTIONROHACELL® IG-F is particularly suitable for prepreg
processing, but can also be used in resin infusion
and RTM processes up to temperatures of 130 °C(266 °F) and pressures of 0.3 MPa (44 psi).

THERMOFORMING AND SHAPING
The thermoformability of ROHACELL® provides
tremendous manufacturing advantages andROHACELL® IG-F is easy to shape by machining.
High precision, pre-shaped and ready-to-use foamcores in complex or simple geometries can besupplied by the ROHACELL® Shapes Department.
