摘要: An ester polyurethane foam is prepared by reacting one or a mixture of hydrophilic polyester polyols with one or more isocyanates and a cell opening surfactant. The cured foam does not require post-foaming processing to achieve a water absorption rate of at least 20 pounds of water per square foot per minute, preferably at least 25 pounds of water per square foot per minute. The foam may be bonded to a substrate to form an absorbent article, such as a sponge, mop head, or a medical or industrial wipe.

摘要: A hydrophilic ester polyurethane foam is flame laminated to a substrate using a thin sacrificial layer, preferably a sacrificial foam layer. The sacrificial layer in the resulting laminate structure has a thickness of 1.5 mm or less, and preferably is substantially burnt away. The resulting laminate exhibits good bond strength along its length and width without loss of liquid wicking and absorptive properties.
