Is Viton heat resistant? The temperature range of Viton™ (FKM/FPM) is considered to be between -20°C and +205°C depending on the grade. It can take even higher or lower temperatures such as -30°C / -45°C
Is Viton heat resistant?
The temperature range of Viton™ (FKM/FPM) is considered to be between -20°C and +205°C depending on the grade. It can take even higher or lower temperatures such as -30°C / -45°C and +230°C, but for short working periods. For further information regarding Viton™ O Rings visit our Material Properties page.
Is Viton good for steam?
Viton Extreme sealing elements exhibit excellent resistance to steam and to attack by an exceptionally broad variety of chemicals and fluids. Sterilization processes used by pharmaceutical, biotechnology, food and beverage manufacturers frequently use steam or caustic chemicals or a combination of both.
Is Viton resistant to ethanol?
Viton is characterized by its: Resistance to degradation by a greater variety of fluids and chemicals than any nonfluorinated elastomer. Excellent resistance to oils, fuels, lubricants, and most mineral acids….Cold.
Chemical | Compatibility |
---|---|
Ethane | A-Excellent |
Ethanol | A-Excellent |
Ethanolamine | D-Severe Effect |
Ether | C-Fair |
Is Viton better than nitrile?
General Suitability: Viton® is best suited for diverse sealing jobs that require high temperature and chemical resistance. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.
How long do Viton O-rings last?
15 Years
O-Ring Shelf Life Recommendation per AS5316
Elastomer Family | ASTM | Shelf Life |
---|---|---|
Fluorocarbon (Viton) | FKM | Unlimited |
Fluorosilicone | FVMQ | Unlimited |
Hydrogenated Nitrile, HNBR or HSN | HNBR | 15 Years |
Nitrile (Buna-N or NBR) | NBR | 15 Years |
Are Viton O-rings fuel resistant?
Viton® O-rings from Parker offer excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals—making it excellent for O-ring, gasket and seal materials.
Is Viton good for hot water?
FKM Viton® rubber is attacked by amines, strong alkalis and many Freon’s. It also has limited resistance to steam, hot water, methanol, ketones, low molecular weight esters and nitro containing compounds like Skydrol, synthetic hydraulic fluids, certain esters and ethers.
Is Viton A Teflon?
Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.
Do O rings wear out?
Abrasion occurs when there is repetitive contact between the O-ring surface and the housing. The excessive friction wears down the sliding contact faces of the O-ring, resulting in wear lines or even deep scratches and breaks. The surface may look dull or glazed, and one side of the O-ring will be worn flat.
What should the temperature of a Viton seal be?
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 are the benefits of using Viton fluoroelastomers?
Products made with Viton™ fluoroelastomers retain their flexibility, shape, and seal when exposed to chemicals and high temperatures. Viton™ FreeFlow™ extrusion process aids also improve processing, increase output, and reduce waste. Demanding environments require components that can perform without downtime or breakdown.
When was the Viton elastomer sealer first used?
Viton fluoroelastomer was introduced in 1957 to meet the needs in the aerospace industry for a high- performance sealing elastomer. Since then, the use of Viton fluoroelastomer has spread quickly to many other industries, especially in the automotive, fluid power, appliance, and chemical industries.
Why do we need Viton ETP extreme seals?
Excellent Resistance to More Chemicals & Solvents– Viton® ETP Extreme. O-rings are used in seals that have to maintain consistent performance in the face of a wide range of temperature extremes. Industries from aerospace to oil refining have systems in place that reach high temperatures, which can destroy or degrade seals quickly.
