What is Anti-Static foam and why should I consider using it?
By the nature of its chemical composition and high surface area, polyurethane foam is prone to the build-up of static charges. This characteristic is overcome with the addition of antistatic chemical additives. These additives are usually incorporated into the foam during the manufacturing process. This assures even distribution throughout the foam for uniform anti-static protection. Anti-static polyurethane foam has become a preferred packaging material for objects which may be harmed by static discharge such as computer hard drives, memory chips and electronic circuitry. Packaging a circuit board in a shielding bag with conventional packaging foam may not be adequate static protection. An anti-static treated polyurethane foam should also be incorporated into the packaging design. Anti-Static foam is available in 1.2# – 2.0# densities and is pink in color.
