Non-Asbestos Gaskets - American Seal and Packing from American Seal's blog

We cut our own custom gaskets to your specifications from high-quality Gasket Materials. Quality brands like AS&P, Durlon, Sichem, Thermoseal, Grafoil, Leader, and Teadit can be found in our inventory of gasket materials. We can cut Garlock, Frenzelit, Sepco, Utex, Interface Solutions, and other brands.

Gasket material is utilized to seal joints between 2 level surfaces. Understanding the demands that the joint may experience is necessary in order to determine what should be placed between flanges or mating pieces. Your gasket’s material must be compatible with the media, temperatures, and pressures it will encounter. Expanded PTFE and Flexible Graphite are the sealing materials with the greatest potential to seal a wide range of applications.

Non-Asbestos Gaskets: These sheets are ideal for steam, oil, and water sealing due to the removal of asbestos from the manufacturing material. We cut Non-Asbestos Gaskets from the materials of all the major manufacturers, such as Duran, Klinger, Armstrong, Tedit, FMI, Johns Manville, Dx Seal, Sepco, Utex, and so on.

Non-Asbestos Gasket Material In the same way that asbestos was available in a variety of grades and was mixed with various rubber compounds, non-asbestos materials are also available. Each fiber acts as a pressure-resistant reinforcement. One of several alternatives to asbestos is present in non-asbestos gaskets. Aramid, Kevlar, fiberglass, and mineral fiber are typical non-asbestos fibers. Since each combination of fiber and elastomer performs differently, there are multiple styles of non-asbestos gaskets.

Kevlar, an aramid fiber, is known to be between two and nine times stronger than asbestos. After that, these fibers blend one-of-a-kind polymers to meet the requirements of numerous applications.

Applications in which Non-Asbestos Gasket materials are frequently used include:

Manufacturing of oil and gas, automobiles, chemicals, mining, petrochemicals, refining, pulp and paper, power generation, and possibly others

The major manufacturers of today include Garlock, Thermoseal (previously Klinger USA), and Gasket Resources Inc. (Duran). Nowadays, the majority of manufacturers produce outside of the country. For North American consumption, Garlock manufactures sheets in Mexico and the United States. Gasket Resources Inc. manufactures in North America, while Thermoseal manufactures internationally and domestically in Ohio (USA). Naturally, sourcing is a dynamic situation that can change.

The filler and elastomer used are the fundamentals, regardless of manufacturer. Although there are no two identical compounds or filler percentages, the fundamental elastomers are: Neoprene, NBR (Buna-N), SBR, or EPDMYou will achieve satisfactory results if you select the Non-Asbestos Gasket material with that elastomer and examine which material you require in accordance with the application. You can now select a competitive brand that will support your application by employing this strategy.

The typical “Binders” are, in general, Neoprene, EPDM, NBR, and SBR

To make things easier, regardless of the manufacturer, the “binder” for each material will be listed. Cross-referencing equivalent materials becomes simpler as a result of this. Tensile Strength (for pressure resistance), Temperature Ratings, and Compression/Recovery Ratings are also important to consider.

Consider the application’s size, temperature, application, media, pressure, and speed (if dynamic) for optimal performance.

When making finished gaskets, take into account bolt loads, the number of bolts, their size, the material, and the torque that is available.
