  • High strength and light tubesheets for hollow fiber membrane permeators
    Patent number: 5234590
    Abstract: A high strength and low weight hollow fiber membrane tubesheet can be achieved by incorporating with the potting material a loading of a nominally spherical filler. The microsphere filler is preferably nonsmooth, hollow and nonporous and may be treated with a surface modifier agent. Other advantages are also obtained including improved machineability with more open, nonsmeared and nondistorted hollow fibers.
