What is Viton plastic?
Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other moulded or extruded products.Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-ringsO-ringsAn O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.https://en.wikipedia.org › wiki › O-ringO-ring – Wikipedia and other moulded or extruded products.10-May-2016
Are Viton O-rings heat resistant?
Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F.
What is Viton polymer?
Viton™ is a fluoropolymer elastomer and synthetic rubber compound, trademarked by DuPont under this brand name. It’s a fluorinated hydrocarbon rubber product with amazing capabilities, designed to withstand even the most challenging of environments.09-Apr-2019
What happens to o-rings in the cold?
Low temperature causes elastomeric materials to contract and become less flexible, even brittle after prolonged exposure. As compression set worsens in low temperatures, it will not return to its original size, which will result in seal leakage and ultimate O-ring failure.
What temperature can O rings withstand?
Why silicone O-rings (VMQ)? Excellent resistance to extreme temperatures -50°C to + 232°C (-58°F to +450°F). Some special compounds resist even higher temperatures. Retention of properties of silicone at high temperature is superior to most other elastic materials.
Are all o-rings heat resistant?
Temperature range: Between -120 degrees Fahrenheit and 450 degrees Fahrenheit, although silicone o-rings have been shown to withstand -175 degrees Fahrenheit during short periods of exposure.
Is Viton better than rubber?
Viton is a synthetic rubber and fluoropolymer elastomer that is used in O-ringsO-ringsAn O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.https://en.wikipedia.org › wiki › O-ringO-ring – Wikipedia and other molded or extruded products. It offers the best fluid resistance of any commercial rubber. At high temperatures, Viton retains good mechanical properties compared to other elastomers.
How hot can Viton o-rings get?
For general-type seals, the optimal viton o-ring temperature range is between -15°F and 450°F in static applications, though it can withstand service temperatures up to 527°F for a short time. Full operation at 450°F will shorten parts’ lifetime more than full operation at -15°F.
What is Viton rubber O-ring?
Viton® is a specific brand of synthetic rubber and fluoropolymer elastomer that is commonly used to manufacture chemical resistant o-rings, seals, and gaskets. The material is categorized as an FKM material under ASTM D1418 and ISO 1629 standards.
Is Viton plastic or rubber?
Viton is a synthetic, floronated hydrocarbon (fluorocarbon) rubber product produced and trademarked by DuPont Performance Elastomers (Viton refers to all types of DuPont fluoro-rubbers). Different kinds of fluoroelastomers possess different swell behaviors, and their processing / compression set resistance.
Are rubber o-rings heat resistant?
EPDM O-Ring Material A synthetic rubber providing excellent chemical resistance and heat resistance. Has an operating temperature range of -60° to 300°F (-51° to 150°C) and a hardness range of 40-90 durometer.
Are nitrile o-rings good for heat?
Nitrile (Buna-N) is a general purpose material suited for petroleum oils, water, and some hydraulic fluids. It is an inexpensive popular seal that is also resistant to tears and abrasive treatment and will function in temperatures between -35 degrees Fahrenheit and 250 degrees Fahrenheit.
How much heat can an o-ring take?
The general accepted range for o-ring use is approximately -75 degrees and 620 degrees Fahrenheit. This wide spectrum is due to the materials from which o-rings can be manufactured.30-Apr-2019
What are Viton O-rings made from?
fluoropolymer elastomer
How is Viton molded?
Either injection molding or compression molding can be used when manufacturing viton rubber. When injection molding is used, the heated rubber is pumped through a machine barrel and comes out a nozzle where it is then injected into a mold.
Is Viton rubber or plastic?
As mentioned, Viton is DuPont’s (now Chemours) brand name for fluorocarbon rubber. This is a synthetic rubber and fluoropolymer elastomer and is commonly used for O-ringsO-ringsAn O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.https://en.wikipedia.org › wiki › O-ringO-ring – Wikipedia and other molded or extruded parts.
What is the highest temperature O-ring?
Silicone or VMP O-rings offer temperature resistance of up to 230°C and some variants of this material can handle up to 300°C. These are commonly used where there is high exposure to UV, ozone and weathering although they are not suitable for use in hot water, chemical or dynamic applications.09-Dec-2020
How are Viton O-rings made?
Best O-ring material for dynamic application
