What is Viton GLT?

What is Viton GLT?

Viton GLT is a fluoroelastomer designed to retain the high heat and the chemical resistance of general use grades of Viton, while improving the low temperature flexibility of the material. Glass transition temperatures (Tg) of materials are indicative of low temperature performance in typical elastomer applications.

What temperature is Viton rated for?

Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours.

Is Viton suitable for hot water?

Viton withstands high temperature better than most other elastomers, and retains its good mechanical properties. High temperature service limits are generally considered to be: 3,000 hr at 232°C. 1,000 hr at 260°C.

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.

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.

Is Viton food grade?

FDA Viton A is well suited for food and lab applications where FDA compliance is required. This material has good chemical resistance, high temperature properties and is resistant to corrosives.

What is the temperature range of Buna N?

Temperature Range:

Standard Compound: -40°C (-40°F) to +110°C (230°F) (+135°C for short periods only)
Special Compounds: -55°C (-67°F) to +110°C (230°F) (+135°C for short periods only – Dry Heat Only)

Is Viton suitable for steam?

Viton Extreme sealing elements exhibit excellent resistance to steam and to attack by an exceptionally broad variety of chemicals and fluids. Seals made with silicone may provide good resistance to a wide variety of cleaning fluids, but have relatively poor steam resistance.

Is Viton resistant to H2S?

This high hardness fluoroelastomer is appropriate for this application temperature and in this temperature is not degraded by heat or oxidation. In terms of resistance to H2S, this high hardness fluoroelastomer is completely resistant and is not attacked chemically.

Is Viton harder than nitrile?

Viton® seals are prone to failure below -15°C in dynamic applications, as they become inflexible and hard. 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.

Is Viton good for diesel?

Since the mid 1990s, manufacturers have specified Viton for seals and gaskets for use in diesel fuel injectors because of its resistance to biodiesel fuels. Excellent compatibility with fresh and contaminated biodiesel, and with ethanol.

What is the maximum temperature of Viton GF?

Maximum temperature resistance of various compounds Type Temperature resistance Kalrez® max. 316°C ZALAK® max. 250°C VITON® GF 200°C VITON® B 200°C VITON® A 200°C HNBR max. 150°C EPDM max. 150°C Neoprène® max. 120°C NBR max. 120°C 3.

What’s the low temperature of a Viton seal?

Cold—Viton™ low temperature performance is dependent on type, with serviceability as low as –31 °C (–24 °F) in dynamic seals and –45 °C (–49 °F) in static seals using Viton™ GLT-S. Viton™ is characterized by its:

What kind of fuel can Viton gflt be used for?

Viton GFLT® recommended for Oxygenated Automotive Fuels (containing MeOH, EtOH, MTBE, etc. and Aromatic Hydrocarbon Process Fluid Chemicals. Compare to Parker V7594B AED resistant, Norsok M710 and NACE T0297 tested Wide chemical resistance including H2S and Oxygenated fuels.

What kind of rubber is Viton made of?

Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. Viton is also known as FKM made of fluoroelastomer one of the most versatile and widely used sealing materials.
