Applications of EPDM Rubber

EPDM (Ethylene Propylene Diene Monomer) is a copolymer of ethylene, propylene and a small amount of non-conjugated dienes. EPDM’s most important feature is its superior oxidation resistance, ozone resistance and corrosion resistance. In addition, due to EPDM’s molecular structure, it has excellent vulcanization properties, can be widely used in automotive parts, waterproof materials for construction, wires, cable sheaths, heat-resistant hoses, tapes, automotive seals and other fields. 

Compared with other general-purpose rubber or special rubber, the main advantages of EPDM rubber are the following:

1. High cost performance.

EPDM has a small raw rubber density and is the most commonly used rubber with the lightest raw rubber density. Moreover, it can absorb a large amount of oil and fillers, and at the same time, it has almost no negative impact on the properties of EPDM, which makes its cost significantly lower.

2. Corrosion resistance.

Since EPDM rubber lacks polarity and has a low degree of protection, it has strong resistance to various acids and bases, alcohols, oils, fats, oxidants, and refrigerants. However, under the influence of financial calculation for a long time, the performance of EPDM hose will be declined.

 

• 3. Wide temperature afford range.

  EPDM rubber products can be used normally at 120°C for a long time, and can be used indirectly or temporarily in the range of 150°C~200°C.

• 

4. Excellent insulation performance

EPDM rubber has excellent electrical insulation properties and corona resistance, and its electrical properties are superior to or close to those of styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene and cross-linked polyethylene.

5. Excellent aging resistance

EPDM rubber has weather resistance, ozone resistance, sunlight resistance, heat resistance, ultraviolet resistance, radiation resistance and other aging resistance properties. When it is used in combination with other unsaturated diene rubbers such as NR, SBR, BR, NBR, and CR, etc. , EPDM can play the role of polymer antioxidant or anti-aging agent.

According to EPDM rubber’s above advantages, some of Shandong Hesper’s rubber hoses use EPDM, like steam rubber hoses(heat resistant rubber hose), food grade rubber hoses(food grade EPDM rubber), chemical rubber hoses(UPE lined), and so on.

Also have other kinds of rubber used for making rubber hoses, we will choose and customize rubber hoses according to the medium, pressure, temperature, etc. Anything in need for rubber hoses, welcome to Contact Us.
