Aflas O-rings and Gaskets

AFLAS_280LR

As a copolymer of tetrafluoroethylene (TFE) and propylene (P), TFE/P provides a unique combination of chemical, heat, and electrical resistance. Chemically, TFE/P resists both acids and bases, as well as steam, amine-based corrosion inhibitors, hydraulic fluids, alcohol, and petroleum fluids. TFE/P is also resistant to ozone and weather. TFE/P typically retains its remarkable chemical resistance even in high temperatures (up to 450° F / 232° C), and tests have shown that electrical resistance actually improves with heat exposure.

The first TFE/P compound to be commercially marketed was Aflas. In a sense, Aflas defined the initial boundaries for base-resistant materials. There are varying grades of Aflas, each with their own molecular weight. Most molded and extruded products are made from Aflas 150P, which has a molecular weight of about 130,000. In comparison, Aflas 100H has a molecular weight of 200,000 and is typically used where high pressures are to be sealed, such as in oil field applications. TFE/P compounds are also widely used in the chemical processing, automotive, and aerospace industries.

Durlon 9000® gasket material

DURLON® 9000/9000N is used extensively in chemical, pulp and paper, food and beverage and the railroad tankcar industries.It has been tested and approved for liquid chlorine, caustics, liquid oxygen, and high purity applications in the pharmaceutical industry (9000N, blood components manufacturing).DURLON® 9000 and 9000N are designed for applications where resistance to highly aggressive chemicals is required. Available in unpigmented white as style 9000N. Both styles 9000 and 9000N, (including branding) conform to FDA requirements.

DURLON® 9000 has been proven through the “Test Protocol” of the Chlorine Institute and is listed as an acceptable gasket material for Dry Chlorine service (both liquid and gaseous) in Pamphlet 95, Edition 3 of the Chlorine Institute. Additionally, DURLON® 9000 was independently tested and approved for Caustics service by a major chemical/chlorine manufacturer. Unlike generic glass fiber filled PTFE, the shape of the fillers used in DURLON® 9000 do not allow wicking which can cause corrosion on flange faces.

 

Genuine Viton®

Today’s industry sometimes operates under extreme conditions. Heat, aggressive media, corrosive gasses and mechanical stress require the utmost performance from your seals. Extreme requirements demand quality assurance and the best materials, in those cases Genuine Viton®, the fluoroelastomer made by DuPont Performance Elastomers is the solution. If safety and quality assurance are a must, Genuine Viton® is the only choice.

Genuine Viton® is manufactured with 100% pure fluoroelastomers and is certified with the Viton® certificate, which is granted by DuPont Performance Elastomers. Genuine Viton® products include: O-Rings, Vulc-O-rings, O-Ring cord, Rubber molded products,Sealants, and sheeting products.

DuPont™ Viton® Fluoroelastomer

Viton O-Rings

Viton® fluoroelastomer is the most specified fluoroelastomer, well known for its excellent (400°F/200°C) heat resistance. Viton® offers excellent resistance to aggressive fuels and chemicals and has worldwide ISO 9000 and ISO/TS 16949 registration.

There are differences between types of Viton® in terms of chemical resistance and mechanical properties. Whether your application is automotive, chemical processing or any number of other industrial applications, there is a particular type of Viton® that best meets your specific performance requirements.

The general purpose types differ primarily from the specialty types in chemical resistance. In the specialty family, the choice is among four types that are tailored for superior fluid resistance, low-temperature performance or combinations of these properties. In order to ensure product integrity and compliance to OSHA 1910.119 in finished parts made of Viton®, our seal helps guarantee that the parts you receive are made from 100% virgin Viton® from DuPont.
