Product introduction

ARCHCELL® IR

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

 

IR (Impact resistance) is a grade with impact resistance requirement. The foam has improved elongation at break and is suitable for parts, such as aircraft wings, radomes, landing gear doors, etc. susceptible to impact damage. While ensuring good impact resistance, this grade can also be compatible the process conditions of 180°C and 0.7 MPa. And it is suitable for various curing processes (autoclave, vacuum infusion, RTM, VARTM, VARI, HP-RTM, etc.). Also, it has good processability and can be easily thermoformed or CNC machined. The fine cell design of this grade and the closed cell structure of the foam ensure a good balance between peel strength and product weight of the sandwich parts.
