Each manufacturer of rubber products consistently linked with the use of rubber compounds. Individual plants rubber products use raw rubber compounds produced by other organizations, some produce such a mixture of their own. For non-rubber materials requires its own rubber compound, with specific qualities. Mostly known imported rubber compounds: Viton, Aflas, Kalrez. Viton is a brand synthetic rubber, commonly used in the O-rings and other molded or extruded products. Name Viton is a registered trademark of the enterprise market DuPont Elastomers llc. Viton is characterized by high resistance to temperature (-40 C to 204 C, even on a temporary basis to 31,192,455 C) and resistance to strength. Viton is resistant to fire, change of weather, the action of oxygen and ozone.
Viton also has a hardness of 75 Shore. Viton uses in many areas. Exemplary suitable for use in food industry, chemical, oil refining and transportation of chemical products. Viton meets the requirements for the aviation industry, for space and engineering industries. Viton plate issued in the form of rolls 1.200 width and length of 10 mb. Plate viton have a thickness from 0,5 mm, 1 mm, 1,5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm and 10 mm.
Viton This class is in conformance with astm D1418 and iso 1629 designation fkm. That this group elastomer is a family comprising copolymers Hexafluoropropylene (HFP), and Vinylidene (Fed or V.F.2), terpolymers of tetrafluoroethylene (OCD), vinylidene fluoride (FRS) and hexafluoropropylene (HFP), as well as perfluoromethylvinylether (PMVE), with special additives. Fluoride content of predominantly common species varies Viton between 66 and 70%. Behavior of rubber compounds in hostile environments chemicals depends on the nature of the base polymer and complex components, consumables for forming the final products (eg, O-rings). These indicators can immeasurably to stand out, if the end-users purchase Viton polymers, including rubber products derived from different sources. Viton ultimately compatible with hydrocarbons (it is a privilege compared with Buna-N, which mainly distributed as a ring material), but nesochitaem with ketones such as acetone and organic acids such as acetic acid. O-rings from Viton, mostly coded as black. Viton O-rings potreblyaelis for some time in equipment for divers who dive with a gas mixture called Nitrox. Moreover, they are less prone to decline in conformance with the terms of increasing the content oxygen.
