A low compression set compound for general-purpose use in O-rings, diaphragms, seals, and other parts used in the process and aircraft industries. It is a carbon black-filled compound with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic an inorganic acids and aldehydes and has good response to temperature cycling effects. A maximum operating temperature of 316°C (600°F) is recommended, with short excursions to higher temperatures possible. This compound is not recommended for use in hot water/steam applications or in contact with certain hot aliphatic amines, ethylene oxide and propylene oxide.

O-ring application range

The O-ring is suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and different liquid and gas media, it can play a sealing role in static or moving state. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. element. O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.
