Nonmetallic Materials: Viton vs EPDM

Product Details: Viton and EPDM are nonmetallic materials used for making gaskets, O-rings, and other rubber parts. Viton is a fluoropolymer (synthetic rubber) known for its high resistance to solvents, acids, and bases. It maintains good mechanical properties and elasticity at high temperatures, and is resistant to oils, chemicals, oxygenated automotive fuel, and atmospheric conditions. EPDM (Ethylene propylene diene monomer) is a durable and versatile synthetic rubber, effective in both high and low temperatures, though it cannot withstand the high temperatures that Viton can. EPDM is resistant to moisture and chemicals but not suitable for hydrocarbons like oils and gasoline.

FKM (Viton®) vs EPDM (EPR) for O-Rings and Seals

Product Details: FFKM (Perfluoroelastomer) and EPDM (Ethylene-Propylene Diene Monomer Rubber) are both used for O-Rings and seals. FFKM operates in a temperature range of -45°C to 204°C, while EPDM operates from -50°C to 150°C. Both materials are resistant to steam, weathering, and sunlight. FFKM offers broad spectrum chemical resistance, including ozone, solvents, aliphatic and chlorinated hydrocarbons, and extreme high temperatures. EPDM is resistant to acids, bases, greases, phosphate ester hydraulic fluids, silicone oils, and glycol brake fluids.

Pros:

Frequently Asked Questions (FAQs)

Frequently Asked Questions

EPDM vs. Viton in China

What are the main differences in temperature tolerance between EPDM and Viton?

When it comes to temperature tolerance, Viton stands out for its high-temperature resistance, handling temperatures up to 260°C (500°F), while EPDM is better suited for lower temperatures, retaining its elastic properties down to -40°C (-40°F). If your application involves high heat, Viton is the clear choice, but for colder environments, EPDM is more suitable.

How do EPDM and Viton differ in terms of chemical resistance?

Viton is unmatched in chemical resistance, compatible with oils, fuels, lubricants, and most acids, including strong acids and solvents. EPDM, on the other hand, is resistant to hot water, steam, detergents, and diluted acids but is not suitable for use with mineral oil products or fuels. So, if you’re dealing with harsh chemicals, Viton is the way to go.

What are the cost implications of choosing Viton over EPDM?

Viton is significantly more expensive than EPDM, costing about 7-8 times more to produce the same amount of material. This makes EPDM a more affordable option, especially for large quantities. However, if budget is not a concern and you need the superior durability and chemical resistance of Viton, it might be worth the extra cost.

Which material is better for outdoor and low-temperature applications?

For outdoor and low-temperature applications, EPDM is generally the better choice. It stands up well to sunlight, rain, and other weather conditions, and it retains its elasticity in very low temperatures. This makes EPDM ideal for applications such as roofing and water systems.

How do the durability and lifespan of EPDM and Viton compare?

Both materials are durable, but they serve different needs. EPDM can last up to 50 years in some applications and is known for its resistance to weathering and low permeability. Viton, while more expensive, offers immense durability and resistance to corrosion, burning, and various chemicals, making it a top choice for demanding and high-stress applications.
