Laird Technologies' new Sculpted Foam UL94 V0 rated Fabric-
Over-Foam product line offers unmatched compression set per-
formance while providing a relatively soft Compression Load
Deflection (CLD) curve.
Low compression set results promote better shielding perform-
ance over the life of the gasket. For extended periods at room
temperature or elevated temperatures (days, weeks, months at
77°F and 158°F [25°C and 70° C]), sculpted foam products yield
better compression set values compared to competition. In
many cases, sculpted foam products perform 50% better.
Lower CLD properties further reduce the potential for distortion
while in application. When the gasket is compressed greater
than the recommended 50%, compression force is reduced by
half. Typical applications include cabinet applications, servers,
and networking equipment.
