Viton Rubber Sheet

 

Product Description

Viton® fluoroelastomer is well known for its excellent resistance to aggressive fuels and chemicals, high heat (400°F/200°C), abrasions and cuts. Viton® also offers superb mechanical properties and can meet many performance specifications. Particularly valued for its excellent heat stability and resistance to aggressive fuels and chemicals, Viton® is the most specified fluoroelastomer for fuel system seals and hoses, O-rings, shaft seals, expansion joints and gaskets. Viton® rubber is good for a broad spectrum of applications in the automotive, chemical processing and industrial markets, including:

  • Chemical resistant gaskets and Viton® seals
  • High temperature Viton® gaskets
  • O-rings
  • Lathe-cut Viton® gaskets and seals

Viton® is a registered trademark of DuPont Performance Elastomers.

Viton® rubber, a specific fluoroelastomer polymer (FPM), was introduced into the aerospace industry in 1957 to fulfill its needs for a high-performance elastomer. Following its introduction, the usage of Viton® spread quickly to other industries including the automotive, appliance, chemical and fluid power industries. Viton® has a strong reputation as a high performance elastomer in very hot and extremely corrosive environments.

Well known for its excellent heat resistance properties (400°F/200°C), Viton® is the most specified fluoroelastomer available for:

  • Fuel system seals & hoses
  • O-rings
  • Shaft seals
  • Expansion joints and gaskets

Because it can extend the thermal resistance of mid-performance elastomers, Viton® has been used extensively in aggressive automobile fuel systems as well as aircraft and chemical processing environments. Viton® was also the first fluoroelastomer to obtain worldwide ISO 9000 registration.

As a product of DuPont elastomers, Viton® rubber can be processed to meet the performance requirements of many automotive, chemical processing and various other industrial applications.

Applications

Viton's® performance reliability under extreme exposure conditions makes it an attractive material to use in many demanding applications. Such performance is a major requisite for parts in the aerospace and aircraft service industries. For example, Viton®O-rings with a service temp. of -45°C to +275°C will also resist the effects of thermal cycling, which are encountered during the rapid ascent and descent of aircraft from the stratosphere.

The high performance properties of Viton® can be seen in many aircraft components including:

  • Radial lip seals used in pumps
  • Manifold gaskets
  • Cap-seals
  • T-Seals
  • O-rings used in line fittings, connectors, valves, pumps, and oil reservoirs
  • Siphon hoses

Additionally, Viton® is the polymer of choice for many of today's advanced fuel and engine systems. Viton's® effectiveness to perform against extremes of heat, chemicals, and fuel mixtures allows it to be used for fuel seals, quick-connect O-rings, head & intake manifold gaskets, fuel injection seals, and advanced fuel hose components.

Advantages of Viton

Temperature Capabilities

Many applications require rubber parts to be stressed by accidental temperature excursions as well as increased operating temperatures to allow for increases in production. In certain instances, Viton® has been known to perform continuously at 204°C and even after short excursions to 315°C. Certain grades of Viton® rubber can also perform equally well in temperatures as low as -40°C.

Resistance to aggressive fluids

Viton® is well known for its ability to perform in a wide range of environments where aggressive fluids are present. By incorporating FPM material, systems can tolerate changes in fluids, allowing for more versatility in a broader range of applications.

Process Purity and Integrity

If FDA compliance is necessary, Timco Rubber has access to certain types of Viton materials that meet FDA requirements for food and pharmaceutical applications.

Compliant with tougher Regulations

As environmental regulations have raised the stakes against emissions, spills and leaks, Viton high performance seals have filled the gap where other elastomers fall short.

Broad Chemical Compatibility

A Quick Comparison

Viton materials are compatible with many important chemicals. Comparing the capabilities of other elastomers to FPM materials like Viton® can be helpful when starting your project or considering a change in materials to increase reliability or to accommodate more severe operating conditions.
