Aluminum is a silver-white, malleable, ductile, light, trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
|
| |
Beryllium Copper
|
|
Beryllium copper alloy physical properties vary depending upon chemical composition and processing. They achieve their properties through alloying elements, cold rolling, and a precipitation hardening heat treatment. Typical physical properties are: - Coefficient of thermal expansion (9.8 x 10-6 inches/inch/°F from 70°F to 400°F)
- Specific heat (0.1 Btu/lb./°F at 68°F)
- Magnetic permeability (1.0)
- Poisson's ratio (0.3)

Butyl
|
|
Butyl is a common term used for the isobutylene isoprene elastomer. It is known for its resistance to water, steam, alkalis, and oxygenated solvents. It has low gas permeation and is capable of providing high-energy absorption (dampening) and good hot tear strength. Suggested operating temperature (-75° to 250° F).

The gasket is made from the elastic, tough, outer tissue of the cork oak. Cork swells when wet to further enhance sealing.
|
| |
Ethylene Propylene (EPDM)
|
|
Ethylene propylene (EPDM) offers good resistance to sunlight, weathering, and ozone. It has poor resistance to petroleum oils and fuel, but offers good heat and compression set resistance. Suggested operating temperature ranges from (-70° to 275° F). Trade names include Nordel® (DuPont Dow Elastomers), Vistalon® (Exxon Mobil Chemical), Epsyn® (DSM Elastomers), Royalene® (Uniroyal Chemical), and Epcar® (B.F. Goodrich).

Fluoroelastomer (FKM - Viton®, Fluorel®, etc.)
|
|
Fluroelastomers are a range of tailorable fluoropolymer elastomers. They are normally black and have high heat, oil, and chemical resistance but indifferent low temperature performance. With the exception of Kalrez® (DuPont Dow Elastomers) perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers. Trade names include Viton® (DuPont Dow Elastomers), Fluorel® and Aflas™ (3M Corporation), and Technoflon® (Montedison).
|
| |
Foam
|
|
These gaskets are manufactured from a foam-based material. They are sometimes bonded to a fabric or other material.
|
| |
Graphite
|
|
Graphite will not leach out or harden and, therefore, last indefinitely in virtually any fluid sealing application. It is also free from corrosion, flow, embrittlement, and aging. This makes graphite gaskets desirable for even extreme conditions. Graphite can withstand temperatures from -200ºC to 1650ºC (as high as 3000ºC in the absence of oxygen). Graphite is resistant to concentrated acids, solvents, and hot oils; is not susceptible to hot or cold flow; and is unaffected by radiation.

| |
Neoprene
|
|
Neoprene is a synthetic rubber that resists degradation from sun, ozone, and weather. It performs well in contact with oils and many chemicals. Neoprene remains useful over a wide temperature range, displays outstanding physical toughness, and resists burning inherently better than exclusively hydrocarbon rubbers. Neoprene also offers resistance to damage caused by flexing and twisting. Suggested operating temperature (-45° to 230° F). Neoprene was originally engineered by DuPont Dow.
|
| |
Nitrile (NBR - Buna-N)
|
|
Nitrile is widely used with most oils, hydraulic fluids, and alcohol due to maintaining good resistance to petroleum hydrocarbons and fuels. Many compound variations are available for specific applications. Suggested operating temperature ranges from (-30° to 275° F). Trade names include Breon® (BP Chemicals), Chemigum® (Goodyear), Hycar® (B F Goodrich), Krynac® (Polysar Ltd.), Nipol® (Zeon Chemicals), Nysyn® NBR, (DSM Elastomers), Paracril® (Uniroyal Chemical), and Perbunan® (Mobay).

Nylon / Polyamide
|
|
Nylon comprises several grades of polyamides, and is a general purpose material in wide use; it is tough, resistant, and has good pressure ratings.
|
| |
Paper
|
|
Paper is normally manufactured from vegetable fibers that are laid down on a fine screen from a water suspension. The fibers are "rough" and "cling" to one another. Almost any fibrous material can be used to make paper.
|
| |
Polyethylene (PE)
|
|
Polyethylene is a semi-crystalline (typically around 50%), whitish, semi-opaque thermoplastic. It is soft, flexible, and tough even at low temperatures, and provides outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance, but is prone to environmental stress cracking. It has poor UV resistance (unless modified) and poor barrier properties, except to water.
|
| |
Polytetrafluoroethylene (PTFE, Teflon®, etc.)
|
|
Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers.
|
| |
Polyurethane / Urethane
|
|
Polyurethane is a diverse class of materials exhibiting good elongation, recovery and toughness properties. They are flexible and have good abrasion resistance. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Trade names include Texin® (Bayer), Adiprene® and Vibrathane® (Uniroyal Chemical), Estane® (B F Goodrich), Genthane® (General Tire and Rubber), Millathane®, and Pellethane® (Dow Chemical).
|
| |
Polyvinyl Chloride (PVC)
|
|
Polyvinyl chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).

Room Temperature Vulcanizing (RTV) Silicone
|
|
Room Temperature Vulcanizing (RTV) silicone is constructed of reactive oil base polymers combined with strengthening mineral fillers. There are two types of RTV: RTV-1 (One-component systems) RTV-1 hardens directly under the action of atmospheric humidity. The curing process begins on the outer surface and progresses through to its core. It is packed in airtight cartridges and is either in a fluid or paste form. RTV-1 silicone has good adhesion, elasticity and durability characteristics. The Shore A hardness can be varied between 18 and 60. Elongation at break can range from 150% up to 700%. They have excellent ageing resistance due to superior resistance to UV radiation and weathering. Industrial RTV-1 products are referred to as CAFs. RTV-2 (Two-component systems) RTV-2 elastomer are two-component products that, when mixed, cure at room temperature to a solid elastomer, a gel, or a flexible foam. RTV-2 remains flexible from -80°C to +250°C. Break down occurs at temperatures above 350°C leaving an inert silica deposit that is nonflammable and non-combustible. They can be used for electrical insulation due to their dielectric properties. Mechanical properties are satisfactory. RTV-2 is used to make flexible molds, as well as many technical parts for industry and paramedical applications.

Silicone Rubber
|
|
Silicones are polymers in which organics groups, such as methyl and phenyl groups, are bonded to the silicone atoms in chains of inorganic siloxanes (-Si-O-Si-). Their properties include heat, cold, and weather resistance; electrical insulation, release, water repellency, and defoaming.
|
| |
Steel
|
|
Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
|
| |
Thermoplastic Elastomer (TPE) / Thermoplastic Vulcanizer (TPV)
|
|
Thermoplastic elastomers (TPEs) are materials that are blended from rubber and plastic. TPEs exhibit rubber-like properties but can be processed using conventional molding or extrusion equipment designed for thermoplastics. Thermoplastic vulcanizers (TPVs) are a type of thermoplastic elastomers. TPVs contain a fully-cured rubber phase (usually EPDM) in a matrix of thermoplastic (usually polypropylene).
