Polyetherimide PEI honeycomb core

 

Polyetherimide is a thermoplastic material. This polymer differs from other thermoplastics because of its high temperature resistance and its capacity to reflect radar.
It is used for the production of stealth panels for military use, for hi-tech panels and as the core material for snow boards.
