EPDM Rubber Properties

Synthetic EPDM rubber is made of ethylene, propylene, and diene monomers. Featuring a molecular structure with a single bond and a chemically saturated backbone, it is extremely resistant to outdoor conditions. Unlike many other rubber materials, EPDM rubber does not bloom, allowing it to maintain colors despite elemental exposure.

The Characteristics of Synthetic EPDM Rubber

Ethylene propylene diene monomer rubber is a popular choice for many applications due to its high levels of flexibility and durability. Characteristics include:

Specific Gravity: .85
Tensile Strength, PSI—Pure Gum: 300
Tensile Strength, PSI—Reinforced: 2500
Practical Shore A Hardness Range: 40-90

Ethylene Propylene Diene Monomer Advantages

The main physical advantage of using EPDM in your production is its outstanding resistance to a variety of factors, substances, and chemicals. It is suitable for many manufacturing methods, including compression molding, transfer molding, and other services. Benefits include:

Excellent resistance to atmosphere aging, oxidation, heat, oxygenated solvent, and moisture
Excellent low temperature flexibility
Good to excellent room temperature and heat resilience
Good to excellent permeability
Good to excellent resistance to diluted and concentrated acids
Good resistance to abrasion and animal or vegetable oils
Fair to good resistance to tears
Fair to good compression set

Limitations of Synthetic EPDM Rubber

EPDM rubber does have a few limitations despite its high-performance capabilities. It is generally attacked by mineral oils, solvents, and aromatic hydrocarbons. Ethylene propylene diene monomer rubber also has poor dielectric properties. It is unsuitable for petro-chemical applications, food and beverage productions, or uses involving an open flame. Exposure to these things can cause EPDM rubber to deteriorate, leading to compromised performances or assembly failure.

Synthetic EPDM Rubber Applications

Synthetic EPDM rubber is an ideal solution for an extensive range of commercial and industrial productions, particularly for parts used outdoors or in other exposed or harsh conditions. It is used extensively in applications such as:

Vehicle seals
Hose
Tubing
Washers
Belts
O-rings
Moisture seals
And much more!
