Down-to-earth role for imidized polymers
Imidized polymers, once thought too exotic for all but aerospace components, now serve in more down-to-earth applications thanks to optimized formulations and broader processing options. Edited by Jean M. Hoffman Terry Swavely, manager of quality at Quadrant EPP's R&D lab, oversees testing
