Neoprene vs EPDM: What's the Difference?

Jan. 05, 2023

Both neoprene and EPDM are materials used in the manufacture of conveyor belt systems. While neoprene is most commonly used in the industry, many companies are turning to EPDM because using it overcomes many of the challenges associated with using neoprene.

 

What is neoprene?

Neoprene is made through the polymerization of chlorine. Characterised by its chemical stability, flexibility over a wide range of temperatures and resistance to degradation, the material was originally intended as a petroleum-based alternative to natural rubber.

 

Its durability and flexibility make neoprene suitable for a wide range of everyday products - such as sports and medical equipment, technical coverings and sleeves, diving suits and safety gloves - as well as for a variety of outdoor applications - including as hoses, gaskets, seals, and gaskets. -including as hoses, gaskets, seals, coatings and linings.

 

Huamei EPDM rubber foams include semi-closed cell supersoft and supersoft foams; closed cell foams and custom foam blends. We can also produce material in a variety of formats such as full rolls, sheets, strip cut lengths and custom gaskets.

 

Benefits of neoprene

The properties of neoprene make it the material of choice for applications requiring

 

Chemical stability

Flexibility over a range of temperatures

Excellent abrasion resistance

Resistance to weathering degradation

Moderate resistance to certain chemicals, acids, greases, fats and oils

 

Huamei EPDM rubber foam is a high-quality closed-cell material commonly used to create air and water-tight seals.

What is EPDM?

EPDM (or ethylene propylene diene monomer) is a variety of synthetic rubbers that offer excellent durability, as well as other properties typically associated with more popular elastomers. Some of its other properties include tear resistance, high tensile strength and compression deformation.

 

Many industries rely on EPDM to keep work processes safe and ensure the delivery of quality products and services, including

 

HVAC

Panel gaskets

Pressure switch tubes


Automotive

Weatherstripping

Hydraulic brake systems

Wire and cable harnesses


Industrial

Belts, Ropes and Tubes

Toxic stinger covers

Electrical insulation

Water supply systems, O-rings and hoses

Benefits of EPDM

The benefits of EPDM over other elastomer options are extensive and include

 

Temperature resistance from -60 to 350 °F

From up to 600% elongation

Recovery

Ability to withstand a wider temperature range than neoprene

Resistance to heat, water, coolants, steam, ozone and sunlight

Resistant to polar materials such as phosphate esters, alcohols and many ketones


Conclusion

While neoprene and EPDM each have their advantages, at Huamei we believe the best of both worlds is obvious. As our standard manufacturing material, EPDM offers consumers greater durability and flexibility, and is suitable for a wider range of applications than its alternatives.


 Huamei is a manufacturer of EPDM rubber foam with low price and high quality, which can play the role of insulation, sealing, heat insulation, sound insulation, weather resistance, etc. for your outdoor work. It has excellent weather resistance to ultraviolet rays and ozone. More about EPDM rubber foam. For more information, check out our page in the drop-down menu.
