Epdm specification pdf

When selecting the best elastomer for a Sealing application, an engineer or designer must be prepared to answer a series of questions about the physical, mechanical and chemical resistance properties required for the seal. Unless the material specifications have been pre-designated, gathering this information about the material's end use and the functional requirement of the seal in the application will help to ensure the material sustains its physical properties through temperature, environmental factors and time.

The best place to start gathering information is by taking a close look at what the application will require from the compound. For replacement products, examine the properties and service conditions of the original material. This information can provide the foundation for what properties are desired, and what are not, in the new material.

For new products, the properties of materials used in similar applications can provide valuable information. Listed brief summaries of the properties of seven of the most versatile polymers, as well as physical and chemical resistance comparison charts. These lists are by no means all-inclusive. However, the majority of sealing solution needs can be met by using these popular materials. For a complete list of polymers, including specialty and high-tech materials, please contact a KAS sales representative.

Silicone Polysiloxane features excellent resistance to ozone, sunlight and oxidation, and is very color stable. It maintains excellent flexibility at low temperatures, has outstanding resistance to high heat, low compression set and is a very good electrical insulator. However, it is not recommended for applications that require abrasion, tear and cut growth resistance, or high tensile strength. It is also not recommended for resistance to oil, gasoline, solvents, alkalis and acids. It is well known for its excellent ozone, weathering and aging resistance.

It also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids and oxygenated solvents, and is very color stable. However, it is not recommended for resistance to oil, gasoline and hydrocarbon solvents. Neoprene Polychloroprene is generally considered an excellent all-purpose elastomer with a solid balance of properties and few limitations.

The polymer has moderate resistance to oils and gasoline. It features good flame resistance, weathers well and has very good resistance to brasion, flex cracking,alkalis and acids. However, neoprene provides poor resistance to aromatic and oxygenated solvents and has limited flexibility at low temperatures.

Nitrile Acrylonitrile-Butadiene has very goodoil, gasoline and abrasion resistance. Resistance to alkalis and acids increases as the nitrile content of the compound increases. Nitrile must be specially compounded for resistance to ozone, sunlight and natural aging. It has poor resistance to oxygenated solvents. Nitrile is superior to neoprene in oil and solvent resistance, but is not recommended for applications where it is exposed to severe weathering. Fluoroelastomers Viton provide premium performance and long-term reliability in very harsh and corrosive environments.

Their exceptional resistance to heat, aging and a broad range of fuels, solvents and chemicals makes them ideal for many demanding aerospace, automotive and industrial applications. Fluoroelastomers also offer excellent resistance to weather, ozone, oxygen and sunlight and are inherently more flame retardant than hydrocarbon rubbers. Fluoroelastomers have poor resistance to ketones, esters, ethers, amines and aqueous bases i. SBR Styrene-Butadiene-Rubber has excellent impact strength, good resilience, tensile strength, abrasion resistance and maintains its flexibility at lower temperatures.

However, it is not the polymer of choice where resistance to oil, gasoline and hydrocarbon solvents is required.Historical Version s - view previous versions of standard.

Installation is important when it comes to putting a single-ply roofing system on a building. Videos have been put together for many of these details, and can be found below.

A fully adhered system provides the highest level of stability and uplift protection, plus a complete line of adhesives available for high-wind areas. With a fast and easy installation, ballasted assemblies are a popular option for the large, open rooftops found on retail stores, warehouses, and other buildings.

The most widely installed system in commercial roofing, mechanically-fastened assemblies are perfect for areas with moderate winds. Using V2T vents, the vent secured system creates a suction effect that strengthens the entire roof and holds the membrane securely in place.

Browse Standards AMS This specification covers an ethylene propylene EPDM rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. This products has been used typically for parts, such as door seals, low-pressure gaskets, dust covers, and shock absorption devices, requiring resistance to weathering, phosphate ester base hydraulic fluids, and polar solvents such as steam, water, and ketones, but usage is not limited to such applications.

This material has fair resistance to all materials listed. Where better resistance to a particular fluid is required, use an AMS for the material compounded specifically for good resistance to that fluid.

EPDM has a great acceptance in the sealing world because of its excellent resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight UV. These compounds also withstand the effect of brake fluids and Skydrol" and other phosphate ester-based hydraulic fluids. EPDM compounds are not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments.

Your information will not be shared with third parties.Ethylene propylene diene monomer EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers 3 — 9 percent which provide cross-linking sites for vulcanization:.

The diene is usually dicyclopentadiene, ethylidene nobornene, or 1,4 hexadiene. These terpolymers can be vulcanized by traditional techniques. They also exhibit excellent electrical insulation, compression set, and low temperature properties, but only fair physical strength properties.

Their resistance to chemicals is generally good. In fact, EPDMs are probably the most water resistant rubbers available. However, they are not compatible with mineral and synthetic di-ester lubricants, and hydrocarbon fuels and solvents.

They also have poor flame resistance. The largest market for EPDMs is the automotive industry. Typical applications include radiator and heater hoses, window and door seals, O-rings and gaskets, accumulator bladders, wire and cable connectors and insulators, diaphragms, and weather stripping. Other major applications are roofing and waterproofing, such as bitumen modifications, facade and parapet sealants, expansion joints, and pool- and tankliners.
