What is EPDM Rubber? – Properties, Applications, Uses

EPDM Rubber

Ethylene Propylene Diene Monomer is a synthetic functional rubber offering exceptional heat and aging resistance with low electrical conductivity.

EPDM Rubber

This rubber can be used as a profitable substitute for silicone when installed in the appropriate environment. Ethylene Propylene Diene Monomer is used across a wide range of Heating, Ventilation, Air, Cooling, and automotive applications.

WHAT IS EPDM ROOFING?

EPDM roofing subsists of a single-layered rubber membrane used with many other elements and, in the case of green roofs and vegetation. While like many other elastomers EPDM is tear-resistant with a tremendous tensile strength, what sets EPDM apart in the terms of its suitability for roofing is its ability to withstand everything that nature can throw at it, from severe heat and cold to ozone and damaging Ultraviolet rays. That makes it unrivaled in the terms of weather resistance.

WHAT ARE THE PROPERTIES OF EPDM?

EPDM Rubber can prevent abrasion, Ultra Violet rays, ozone, and weather, therefore it is the most waterproof rubber available in the market.

EPDM is resilient and has a low electrical conductivity and complies easily with metals. It is also flexible with a 600 percent elongation and tensile range of 500 to 2500 psi, functioning well in temperatures from minus 45 degrees Celcius to 177 degrees Celsius.

In addition to this, Ethylene Propylene Diene Monomer insulates and slashes outdoor noise, The main reason why this rubber is frequently used in the automotive industry.

WHAT IS EPDM RUBBER USED FOR?

Ethylene Propylene Diene Monomer is used as a more reasonable alternative to silicone rubber for parts that will have a lot of outdoor exposure or electrical insulation.

1. AUTOMOTIVE INDUSTRY:-

This is the most common application of Ethylene Propylene diene Monomer due to its flexibility, resiliency and weather ability. It can be found in vehicle weather stripping, seals, wires and brake systems.

It is also synthesized with other elements to make fender extensions and car bumpers.

2.INDUSTRIAL 

This rubber is used in industrial applications for its electrical insulating and waterproofing properties. EPDM can be found in water systems Orings, gaskets, electrical insulators and connectors for wires and cables.

3. CONSTRUCTION –

Ethylene Propylene diene monomer is used in construction applications due to its weather and waterproofing abilities, roofing is the primary application for this rubber.

Anyhow, it is also utilized for sealant, expansion joints, pools, and tank liners or waterproof coating for bitumen and RV roof.

4. HVAC –

This industry uses EPDM in the form of grommets, tubing, gaskets and insulation because of its weather ability and temperature resistance.

HOW LONG DOES EPDM LAST?

It hinges on the application it is used in as well as the conditions under which it is working. When regularly working at extreme temperatures, EPDM’s lifespan will shrink a lot.

Anyhow, if properly taken care of, Ethylene Propylene Diene Monomer products can last for some decades. EPDM Roofing can last around 30 to 50 years and the liners can also last for at least twenty years.

IS EPDM RUBBER TOXIC?

Ethylene Propylene Diene Monomer is leach resistant and contains NO toxic substances, so it is the perfect choice for fish, plants, birds and associated wildlife. A Major reason that EPDM is not harmful to the environment is its long life.

The material will last for half a century and will not be broken in this time. Once the material has exceeded its maximum life capacity, it is recyclable and the rubber gets a new life in the form of some other product.

ADVANTAGES AND DISADVANTAGES OF EPDM

ADVANTAGES OF EPDM RUBBER

Ethylene propylene diene monomer has exceptional resistance to water and Ultra Violet rays or oxidation. The temperature and weathering properties are also impressive.

These factors make this rubber ideal for use in water and it is usually the rubber of choice. EPDM is a good all-around material widely used as an affordable polymer with superb processing abilities.

DISADVANTAGES OF EPDM RUBBER

EPDM has disappointing compatibility with oils, gasoline, and concentrated acids. The inert nature of this material also means that it is crucial to adhere and this can be a limitation.

In mould vulcanized bonding to a substrate is the best method of assuring reliable bond and adhesive solutions that provide good bonds but correct preparation and application are critical with this polymer. It is not flame resistant, hence not recommended for food applications.

CONCLUSION:

Ethylene propylene diene monomer is one of the best rubber available in the market due to its extreme durability, weather ability and temperature resistance.

We hope that this guide, covering its properties, advantages, disadvantages and applications has been useful for you. EPDM rubber is only one of the certain kinds of rubber used in the industry.
