Epoxy Systems for Suspension Components

Our award-winning systems for glass-reinforced leaf springs, coil springs and other dynamically loaded parts are suitable for short cycle time RTM, prepreg, towpreg and filament winding processes. Benefits include good dynamic behavior and fatigue performance, good chemical resistance and high Tg. These systems save energy twice—during manufacture, and by reducing vehicle weight.
