  • Process for making high-pressure sheet gasketing materials
    Patent number: 8871841
    Abstract: A method for making high-pressure sheet gasketing material is provided that employs an elastomer, such as natural rubber and/or acylonitrile-butadiene rubber. Tert-butyl acetate is added to dissolve the elastomer. Other components may then be mixed with the dissolved elastomer and may include, for example, antioxidants, colorants, curing agents, curing accelerators, reinforcing fillers, and fibers such as organic and/or mineral fibers. The resulting dough may be formed into a high-pressure sheets, for use as gasketing material, using a two-roll sheeter machine, or the like.
    Type: Grant

    Date of Patent: October 28, 2014
    Assignee: Garlock Sealing Technologies, LLC

  • Compressed gasketing material
    Patent number: 8114934
    Abstract: A compressed sheet gasketing material is provided with a combination of high elastomer content and high swelling medium content. In one aspect, the swelling medium may include bentonite clay and may be provided a weight percentage that varies from 30 to 60%. In another aspect, a rubber content weight percentage that varies from 20 to 30% provides a relatively high compressibility. The compressed sheet gasketing material may further include one or more various fibers commonly used in high pressure sheet formulations.
