Abstract
A static dissipative flexible polyurethane foam is formed under free rise expansion conditions from a polyether graft polyol, a polyether polyol or ester polyol and an isocyanate, wherein one or more anti-static additives are incorporated into the reaction mix in an amount from 0.10 to 20 parts by weight. Water is added in an amount of from 0.2 to 1.0 parts per weight. Upon curing, the foam has a density in the range of 6 to 20 pounds per cubic foot, a surface resistivity below 1 x 10.sup.11 ohms/square, and a pore size in the range of 100 to 250 pores per inch. The foam may be fabricated (cut or shaped) to form a shaped article, such as a roller, a clean room wipe, a cosmetic applicator or a packaging element.
