Its the toughest of the Foam material use for RC Aircraft this rubber like foam can resist hard impact damage , best use for experimental designs as well as UAV or sport wings. Proper ribbing construction can make this material standalone w/o stiffening. the only trade off is prolong exposure to heat. (if you use glue sticks the material would soften and melt the glue off.) but returns to normal stiffness onces cool down.
