Product introduction

ACRYLICFOAM® EP

ACRYLICFOAM® is a closed-cell rigid PMI (Polymethacrylimide) foam, which used as the core of lightweight sandwich structure.

EP is an improved and economic grade. It is suitable for low-medium temperature curing epoxy resin system and suitable (based on density) for various curing processes (Autoclave, vacuum infusion, RTM, VARTM, VARI, HP-RTM, etc.). It also can be easily thermoformed or CNC machined. The design of the cells in this grade and the closed cell structure of the foam ensure a good balance between peel strength and product weight when building sandwich structure parts.
