  • Oil sorbent material made by opening cells of a closed cell foam
    Patent number: 4183984
    Abstract: Closed cells in a flexible foam structure and preferably a polyethylene foam sheet are opened, suitably by needle punching, to increase the oil sorbency of the pad. One embodiment uses needle punching which does not pass all the way through the sheet, thus blocking passage of oil therethrough. Another embodiment employs unpunched strips for prevention of migration of the oil or for buoyancy purposes.
