Gasket Material Selection
Our extensive experience with a wide variety of gasket materials enables us to be able to work with you to determine the optimum material for your application.
Excelsior offers a wide variety of gasket materials to meet the needs of any job and is a preferred distributor for a number of material manufacturers. We maintain a large inventory of materials and are always adding new and high-temperature gasket materials to meet customer needs.
Cloth-Inserted RubberMaterial Details
Rubber is also commonly used with cloth or fabric-inserts. Common fabrics include cotton, nylon, polyester and fiberglass. These products will have 1 or more layers of fabric throughout the thickness of the rubber. Generally, the fabric is added to increase stability where mechanical fastening is necessary.
Corks & Cork RubberMaterial Details
Cork and rubber gaskets are commonly used in sealing flanges where there is contact with oil, fuel or natural gas and where bolting pressure is somewhat low. Both cork and cork/rubber gaskets are excellent when mating surfaces have possible imperfections or don't perfectly mate as they will conform to the surfaces.
- Cork composition
- Cork - friction
- Cork / Buna-N
- Cork & nitrile, neoprene or silicone
Electrical Insulating MaterialsMaterial Details
Gaskets are commonly used in and around electrical applications. These electrical insulation materials are used to prevent or restrict the flow of electrical current; prevent electrical arcing; prevent electrical conductors from contacting unwanted objects; and other general electrical insulation applications.
EMI Insulating & Shielding MaterialsMaterial Details
EMI stands for electromagnetic interference. Electromagnetic energy can come from many sources and without proper protection, can result in the failure of certain electrical systems. EMI shielding gaskets can protect electronic systems against electromagnetic interference.
- Metal impregnated silicone
- Metal foils
FDA Approved RubberMaterial Details
The FDA regulates materials that are in contact with food or beverages during processing, packaging or storage. We offer a number of different materials that are certified to meet FDA standards.
Felt remains a popular material used in certain gasketing applications. Felt is supplied in both wool and synthetic options. Wool felt is made from pressing premium wool fibers together. This type of product is commonly referred to as “pressed” felt.
- Flame resistance
- Material remains unchanged with continued exposure to many oils
- High strength and excellent wear properties
- Excellent insulator against sound, temperature and vibration
- It does not fray or come apart
Fiber and PaperMaterial Details
Fiber-based gaskets are one of the most broadly used categories of products. Fiber products can offer a very wide range of benefits and fit a wide range of applications.
- Barrier Paper
- Ceramic fiber
- Vegetable fiber (Detroiter)
- Vulcanized fiber - black, grey & red
Polyurethane foam is a softer, open-cell foam that allows air and liquid to penetrate through the foam. Polyethylene foam is a more firm closed-cell foam that is more dense and rigid.
Non-Asbestos Compressed & Beater Mix AdditionsMaterial Details
There is a broad range of engineered materials used for gasketing that are referred to as compressed sheet or non-asbestos. Generally, these materials are made with certain fibers (ie Aramid fiber) and other fillers with a rubber binder. Users will choose a rubber binder suitable for their application.
- Many brands and styles available
Other Gasket MaterialMaterial Details
Excelsior, Inc. offers a number of other materials to give you more options for your gasket manufacturing needs.
- Teflon Coated Fiberglass
- Grafoil / Flexible Graphite
- AMS, FDA, NSF, Mil Spec and UL listed
- Nomex/Kapton laminates
Solid RubberMaterial Details
Rubber is probably the most widely used gasket material. Rubber is offered in many different styles and grades to meet many applications’ needs. In addition, rubber is commonly available “off the shelf” in most styles, grades and thicknesses.
Synthetic rubbers are generally made from petroleum-based by-products. Alternatively, natural rubber is derived from latex from Rubber trees which are found in Thailand and Indonesia.
Sponge RubberMaterial Details
Closed cell sponge rubber gaskets use chemicals and heat to expand the material and create a “soft” or sponge rubber. Sponge rubber is generally sold by density or firmness. The primary types of solid rubber are also used to create sponge rubber. Sponge rubber is much more compressible than solid rubber and carries many of the benefits of solid rubber.
- EPDM sponge
- Neoprene sponge
- Neo / EPDM . SBR sponge
- PVC / Nitrile sponge
- Silicone sponge
- Viton sponge
Material Selection GuideMaterial Details
The guide will assist you in gasket material selection, gasket design and gasket application. Selecting the right gasket design and material is critical to the effective operation of a reliable joint. It involves taking into account a wide variety of application parameters such as function, temperature, fluid or gas, pressure, UV & Ozone, EMI/RFI requirements and other considerations such as FDA, NSF or WRAS requirements.
