Difference Between EPDM vs Neoprene Rubber – Best Guide

EPDM vs Neoprene

EPDM vs Neoprene:- EPDM and Neoprene are both synthetic rubbers that are used for a number of purposes. They vary mainly in price and a few main properties.

EPDM vs Neoprene

Although EPDM is less expensive, noise-resistant, and a strong electrical insulator, neoprene is a chemical, oil, and fire-resistant thermal insulator. Gaskets, conveyor belts, and outdoor applications are all popular uses for both rubbers.

WHAT IS EPDM RUBBER?

Ethylene Propylene Diene Monomer rubber has a single bond molecular structure and is made up of ethylene, propylene and diene monomers. Oil, gas and hydrocarbon solvents are susceptible but alkalis, acids and oxygenated solvents are immune.

EPDM provides noise control while being resistant to sun, cold, ozone, water, and weathering. It also acts as an excellent electrical insulator.

These characteristics make it a common option for roofing, sealant, gaskets, and weather stripping in the automotive, Heating, Ventilation, Air, Cooling, and roofing industries.

WHAT IS NEOPRENE RUBBER?

Neoprene, also known as chloroprene is a polymer made up of carbon, hydrogen and chlorine. It’s oil, alkali and acid resistant, much like EPDM but it’s vulnerable to aromatic and oxygenated solvents.

Many other rubbers are less resistant to corrosion and degradation than neoprene. It’s also weather-resistant and fire-resistant, as well as thermally insulating and waterproofing.

These characteristics make it a popular choice for marine equipment and diving suits, but it’s also used in latex-free rubber gloves, roofing, and other applications that require moderate chemical and oil resistance.

Corrosion-resistant coatings, high-pressure adhesives, gaskets, and belts, vibration mounts, and weather stripping are all common uses for neoprene.

EPDM VS NEOPRENE

Although EPDM is preferred for its electrical and noise resistance, neoprene is preferred for its thermal insulation and chemical, oil and fire resistance. Both rubbers can be extruded and shaped and are suitable for general purpose applications.

They have similar low-temperature limits and have medium to decent tear resistance, better abrasion resistance, and outstanding weathering properties.

They are more suited for particular applications due to certain fundamental differences. Ethylene Propylene Diene Monomer is the less costly of the two rubbers for some uses.

EPDM can withstand temperatures of up to 350 degrees Fahrenheit, while neoprene can only withstand temperatures of up to 225 degrees Fahrenheit.

It is much more ozone-free and resistant to steam. EPDM, unlike neoprene, expands when exposed to fuel oil, fluid or solvent.

Neoprene, on the other hand, has chemical and fluid resistance properties that EPDM lacks, such as improved oil and gas resistance. It also has a higher flame resistance than EPDM.

However, since neoprene is the more expensive rubber, these properties come at a price.

CONCLUSION

We hope that now that you have learned about the basic properties of Ethylene Propylene Diene Monomer and neoprene, as well as the discrepancies between them, you will be able to work more effectively with these materials.

However, EPDM and neoprene are only two of the forms of rubber that are widely used. Check out our buying guide on the most widely used forms of rubber in the industry to learn more about other rubbers like butyl, nitrile, and silicone rubber.
