Description
Premium 31 IG-F is a high-performance PMI (polymethacrylimide) foam with a very fine closed-cell structure. This closed-cell foam only takes up resin in the exposed cut cells at the surface, preventing excess resin from infiltrating further into the foam and resulting in very low surface resin consumption. Compared to closed-cell PVC foam, PMI foam offers better mechanical properties, with approximately 15% higher compressive strength, higher processing temperatures, and significantly lower resin consumption.
This foam is compatible with all common resin systems including epoxy, vinyl ester, and polyester. It is easily machined, milled, and cut using conventional tools designed for wood or plastic, while thinner sheets can be cut by hand. Radii down to twice the sheet thickness can be molded using thermoforming at around 180°C, where the foam becomes thermoplastic.
We supply this foam in two densities: 31 IG-F at 32kg/m³ for lightweight applications with skins under 0.5mm, and 71 IG-F at 75kg/m³, which has almost three times the mechanical strength and stiffness of the 31, making it ideal for heavier loaded panels with thicker skins such as floors, decks, and chassis elements. Typical applications for this foam include aerospace, automotive, medical, marine, wind power technologies, and recreation and sporting goods.
