    • 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 (96.1 to 320.4 kg/m 3 ), a surface resistivity below 1 x 10 11 ohms/square, and a pore size in the range of 100 to 250 pores per inch (39.4 to 98.4 pores per cm). 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.
    • 在自由升温膨胀条件下由聚醚接枝多元醇,聚醚多元醇或酯多元醇和异氰酸酯形成静电消散的柔性聚氨酯泡沫,其中一种或多种抗静电添加剂以0.10至20的量掺入反应混合物中 重量份。 水的添加量为0.2-1.0重量份。 固化后,泡沫的密度范围为6至20磅/立方英尺(96.1至320.4千克/平方米),表面电阻率低于1×10 11欧姆/平方厘米,孔径 范围为100至250个孔/英寸(39.4至98.4个孔/厘米)。 泡沫可以被制造(切割或成形)以形成成形制品,例如辊,洁净室擦拭物,化妆品涂抹器或包装元件。
