Process for making high-pressure sheet gasketing materials
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.
Gasket materials having releasable protective layers formed thereon and method of making the same are disclosed. The releasable protective layers provided added strength to the gasket materials to help prevent cracks and chips in the gasket materials that can occur during handling, transporting, and cutting of gasket material. The protective layers can include releasing agent to ensure the protective layers can be removed from the gasket materials prior to being used.

A labyrinth sealing device is disclosed for use between a rotating shaft and a bearing housing, hi some embodiments;, an internal stator engages the housing and a rotor engages the shaft. A labyrinth pathway is defined between the rotor and stator to prevent the migration of lubricants and/or contaminatnts in either direction. The rotor acts as a running surface for the sealing element, but may also with a ground surface of the rotor to provide a pump that continuously draws lubricant away from the sealing Mp toward a sump. In another embodiment, the stator and sealing element are combined as a sealing element formed from a sealing material. A recess in the sealing lip creates a pressure differential at the sealing surface and minimizes wear.

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.
A molded discrete low stress gasket is constructed of restructured filled PTFE for use in corrosive or severe chemical environments under relatively low bolt loads. The gasket has a gasket surface and includes a raised outer sealing ring and a raised inner sealing ring. The gasket may constructed from a restructured filled PTFE material, with the sealing rings deforming at lower pressures than the remaining portions of the gasket.
A high temperature dynamic seal and methods of assembly and use are presented. In one embodiment, the dynamic seal is provided as a rotating seal, which includes a stationary ring and rotating ring assembly, with a seal ring that is positioned between the stationary ring member and the rotating ring assembly. In some embodiments, one or more high temperature seals create a seal between the stationary ring member and a device in which the dynamic seal is used. Similarly one or more high temperature seals create a seal between the rotating ring assembly and a rotating shaft of the device. In one aspect, one or more of the high temperature seals are formed from a metallic material with various cross-sectional shapes.

A bearing isolator assembly for sealing a rotating shaft with a porous sealing element including a rotor configured to sealingly engage with a shaft, and a stator configured to sealingly engage with a housing of an assembly. The rotor and stator are configured to engage with each other to define a labyrinthine pathway and one or more cavities, in which may be disposed a unitizing element and a porous sealing element. The porous sealing element provides a barrier to particulate contaminants from entering the interior of the housing, and to prevent egress of lubricants from the interior of the housing. The unitizing element limits axial and/or radial movement of the rotor with respect to the stator, and helps prevent wear of the rotor and/or stator by helping prevent the rotor from contacting the stator during operation.
