In 2015, the DuPont company restructured its different business units as part

of a new global strategy. The Performance Chemical division was transferred

to The Chemours Company, the current owner of the Viton™ brand.

Viton™ fluoroelastomers were introduced in 1957 to meet the needs of the

aerospace industry that required a high-performance seal elastomer. Since

then, the use of Viton™ fluoroelastomers has expanded to many other

industries, especially in the automotive, chemical, oil and energy sectors. With

over a century of proven performance, Viton™ fluoroelastomers have gained

a reputation for outstanding performance in high temperature and extremely

corrosive environments.

Products based on Viton™ provide an exceptional balance of physical

properties, with excellent performance at extreme temperatures.

High temperature. Compared to most other elastomers, Viton™ is better able

to withstand high temperature, while simultaneously retaining its mechanical

properties. Its resistance to oils and chemicals is also essentially unaffected

by high temperatures. Viton™ high temperature service limits are considered

to be:

▪ 10.000 hours at 204°C (400 °F).

▪ 3.000 hours at 232°C (450 °F).

▪ 1.000 hours at 260°C (500 °F).

▪ 240 hours at 288°C (550 °F).

▪ 48 hours at 315°C (600 °F).

Low temperature. Viton™ low temperature performance depends on the

type, with serviceability as low as –31°C in dynamic applications and –45°C in

static applications using Viton™ GLT-S.

Introduction

▪ Resistance to degradation by a greater variety of fluids and chemicals

compared to any other non-fluorinated elastomer. Excellent resistance to

oils, fuels, lubricants, and most mineral acids.

▪ Extremely low permeability to a broad range of substances, including

particularly its resistance to oxygenated oxygenated hydrocarbons.

▪ Resistance to aliphatic, aromatic hydrocarbons that dissolve other rubbers.

▪ Exceptionally good resistance to compression set, even at high

temperatures.

▪ Exceptionally good resistance to atmospheric oxidation, ozone and UVA

rays. Excellent response to fungus and mould

▪ Good electrical properties in low voltage, low frequency applications.

▪ Fire resistant. Inherently more flame resistant than other, non-fluorinated

hydrocarbon elastomers.

▪ The standard types or families of Viton™ are designated as A, B, or F based

on their resistance to fluids and chemicals The differences in resistance to

fluids (mineral acids or aliphatic and aromatic hydrocarbons) are the result

of different levels of fluorine content in the polymer.

Introduction

6

The higher the fluorine content, the better the resistance to fluids (lower volume

swell). This can be seen in the following table (see volume change in Methanol

at 23°C). However, as the fluorine content increases, the low temperature

flexibility of the polymer decreases. So when it comes to select the type of

Viton™, a compromise has to be made between fluid resistance and low

temperature flexibility

*Nominal test values, these are not intended to serve as specifications.

For those applications that require the best performance in both fluid resistance

and low temperature flexibility, a number of specialty types of Viton™ have

been developed that contain a co-polymerized fluorinated vinyl ether monomer.

Polymers that contain this monomer exhibit significantly improved low

temperature flexibility, compared to standard types of Viton™ (A, B & F).

Choice of VITONTM type

Viton™ GLT-S provides the same excellent resistance to heat and fluids

as Viton™ A. Viton™ GFLT-S, as with Viton™ GLT-S, exhibits significantly

improved low temperature flex characteristics compared to standard types of

Viton™ In addition, Viton™ GFLT-S provides the same superior resistance to

fluids as Viton™ F.

The ETP types of Viton™ exhibit the same resistance as A, B, and F types of

Viton™. However, unlike conventional fluoroelastomers, ETP types of Viton™

also provide excellent resistance to low molecular weight esters, aldehydes

and ketones. In addition, these unique polymers are inherently resistant to

attack by base and, thus, provide excellent resistance to volume swell and

property loss in highly caustic solutions and amines.

Viton

The Viton™ F family was designed for use with oxygenated fuels, modern

lubricants and blended aggressive chemical agents. Given that new chemicals

and fuels are being developed, Chemours is leading new developments in the

Viton™ F family of sealing products.

Viton™ F offers superior fluid resistance and very low permeation in very

aggressive environments.

Viton™ F offers excellent resistance to fluids that Viton™ A and B types cannot

adequately resist. Viton™ F are resistant to oxygenated fuels containing

(MeOH, EtOH, MTBE), engine lubricants (SE-SF and SG-SH grades), aromatic

hydrocarbon process fluids, chemicals and concentrated mineral acids.

▪ TH-1210-FBC: Viton™ F (with a Bisphenol cure). Offers the best fluid

resistance at a very affordable price.

▪ TH-7070-FGC: Viton™ GF peroxide curable offers good resistance to

aqueous fluids: Water, Steam, and Mineral Acids. (S04H2, N03H, ClH, etc.).

▪ TH501-GFLC: Viton™ GFLT Peroxide Curable offers exceptional chemical

resistance and maintains flexibility in low temperature applications -40°C.

VITONTM F

12

Viton™ Extreme offers more universal chemical resistance than any other

grade of Viton™ or PTFE elastomers. In addition, Viton™ Extreme offers

similar base resistance to VTR 7430 (Viton™ Base Resistant).

Viton™ Extreme was originally developed to resist H2S found in the

environments surrounding the oil prospecting fields. However, it has become

widely used in the Chemical Processes, Oil Refining, and in the Semiconductor

and Chemical Transportation industry.

The various fuels of today that contain oxygenated additives such as MTBE,

TAME, ETBE as well as alcohols cause serious sealing problems that Viton™

Extreme can solve without having to use other costly perfluoroelastomers

(Kalrez).

Thanks to their superior performance and cost-effectiveness, seals made from

Viton™ Extreme are an excellent choice for such industries as:

▪ Analytical and process instruments

▪ Chemical industry processes

– Agricultural chemicals and fertilizers

– Pharmaceutical industry

– Polymer production

– Inorganic chemicals

– Organic chemicals

▪ Chemical transport

▪ Oil and Gas exploration

▪ Paint and Coating operations
