Industrial-grade performance for versatile, reliable results
ROHACELL® IG/IG-F
ROHACELL® IG-F structural foam is a closed-cell rigid foam based on polymethacrylimide (PMI) chemistry and contains no CFC's. The “IG” in ROHACELL® IG-F stands for “Industrial grade.” It is the standard product in our range of rigid 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 minimal resin at the surface where the cells have been cut open. Less resin take-up during part processing means less final part weight and overall cost.

Thermoforming and shaping
The thermoformability of ROHACELL® provides tremendous manufacturing advantages, and ROHACELL® IG-F is easy to shape by machining. High precision, pre-shaped, and ready-to-use foam cores in complex or simple geometries can be supplied by the ROHACELL® Shapes Department.
Resin absorption and cell structure
ROHACELL® IG-F features a finer cell structure compared to standard grades, ensuring reduced resin uptake at the surface, which translates to lighter final components and lower material costs.
Processing and compatibility
Designed for temperatures up to 130 °C and pressures up to 0.3 MPa, ROHACELL® IG-F is suitable for prepreg processing, resin infusion, and RTM methods. Its compatibility with diverse processes makes it versatile for industrial, medical, and automotive applications.
