PORON® 4790-79 (Display Back Pad Foam)
Thin polyurethane foam for display protection, vibration control, and shock absorption
PORON® 4790-79 Display Back Pad is a firm microcellular polyurethane foam engineered for vibration management and shock absorption in portable electronic applications. Its thin profile makes it a strong choice for designs that need excellent energy management without adding unnecessary bulk.
By absorbing and distributing impact energy, PORON® 4790-79 helps protect delicate displays and maintain structural integrity in compact assemblies. It is especially useful in designs where thin construction, repeatable shock protection, and long-term compression performance are critical.
