Rohacell IG-F

ROHACELL® IG-F is one of the most commonly used grades of PMI material. IG-F are particularly suitable for prepreg applications, but can also be processed in resin infusion or RTM technology up to temperatures of 130°C and pressures of 0.3 MPa. What is important, ROHACELL® IG-F grade is also easy to shape by machining. The higher the density, the stronger the material and easier to machined.

Description

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.

PROCESSING AND PRODUCTION

ROHACELL®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 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 Chem-craft Shapes Department.
