Desco's conductive foam is a non-abrasive, open-cell (closed cell in cross linked) polyurethane foam compounded for permanent ESD control properties, the black conductive foam's Rtt range of 10^3 to 10^6 allows it to be used with ESD susceptible products. - Minimizes charge generation, material will conduct charges if grounded. Ideal for long term storage. Will not affect the solderability of device leads. Antistatic, low tribocharging.
