Method of maintaining a low residue open-cell felted foam |
摘要 |
Open-Cell urethane foam is thoroughly dried in a convection oven or controlled atmosphere and then compressed with heat to a felt immediately. Alternatively, the dried foam is sealed in a plastic bag until the felting step. The amount of non-volatile residue is significantly reduced to produce a foam for use to contain ink in an ink jet cartridge.
