PMI Foam – High-performance structural core

PMI (Polymethacrylimide) foam is a high-performance closed-cell structural core developed for lightweight composite structures requiring exceptional mechanical properties, thermal stability and dimensional accuracy.

Available in a wide range of densities, PMI foam combines outstanding compressive strength, high stiffness and low weight, making it the preferred solution for demanding applications in aerospace, motorsport, automotive, marine, defence and high-performance sports equipment.

Its optimized cell structure ensures an excellent balance between low resin absorption and strong skin-to-core adhesion, making it particularly suitable for vacuum infusion, prepreg, vacuum bagging, autoclave, RTM (Resin Transfer Moulding) and VARTM (Vacuum Assisted Resin Transfer Moulding) processes. PMI foam also enables one-shot sandwich manufacturing (co-curing), reducing production time and improving process efficiency.

The material can be easily thermoformed or CNC machined to produce complex geometries and ready-to-use core kits tailored to specific project requirements.

Available in different densities to meet a wide range of structural and manufacturing needs.
