EPDM rubber – Ethylene propylene diene rubber is a terpolymer. It is obtained from ethylene-propylene-diene monomers. This rubber is produced by the action of the third monomer. It is cross-linked in the process of sulfur or peroxide vulcanization.
What does EPDM stand for?
EPDM abbreviation comes from the English language. It stands for ethylene propylene diene monomer (rubber), i.e. ethylene propylene diene rubber.
EPDM rubber – Properties
EPDM rubber has an exceptionally good ability to reverse deformation under the influence of mechanical forces. The deformation is created while maintaining the structure of the continuity of the material. This property does not change, even in the face of temperatures up to +110 degrees. EPDM rubber remains flexible even in a collision with a temperature of 40 degrees below zero.
EPDM temperature range
The most common use of a rubber compound with EPDM is for the following temperature range:
-40 ° C to + 110 ° C
It is worth noting that the offer for specialist O-rings available at POWER Rubber includes EPDM O-rings resistant up to +150 °C
EPDM rubber Resistance
Ethylene-propylene-diene rubber is also characterized by many properties and good resistance to many factors, such as:
- Hot water and steam up to +150 degrees. Celsius, and in the case of special materials up to +180 Degrees
- Brake oils based on glycol up to 150 Degrees
- Organic and inorganic acids
- Basics: potassium and sodium, and cleaning agents
- Hydraulic fluids based on phosphate esters
- Silicone based oils and greases
- Polar solvents such as ketones, esters and alcohols
- Skydrol – 500 and 7000
- The action of ozone and UV radiation
- Weathering of aging
- It does not discolor or stain other materials
Moreover, EPDM rubber is distinguished by its low elasticity. Hence, it is also resistant to abrasion compared to other types of rubbers.
However, ethylene-propylene-diene rubber is not resistant to the action of:
- Products based on mineral oils such as greases, oils and fuels
- Aliphatic, aromatic and chlorinated hydrocarbons
The trade names under which EPDM rubber is hidden are:
Application of EPDM rubber
Thanks to its wide range of properties, ethylene-propylene-diene rubber has been used in many industries and industries. In the automotive production, he is responsible for creating seals for windows and doors, shock-absorbing elements and for construction. Including sealing profiles for plastic joinery, hydraulic hoses, cable covers and roofing. In the automotive industry, it is also used for the production of tires, tubes, bumpers, etc. With its help, surfaces are also created for the so-called safe playgrounds. Valued in the water installation industry. It is used for sealing in the food industry. Compounds based on EPDM rubber are used in the production of automatic washing machines. Thanks to its use, elements for shock-absorbing and damping vibrations are also created. Ethylene-propylene-diene rubber is especially valued primarily in the insulation of roofs and terraces. Thanks to the use of EPDM rubber, roofs and terraces are guaranteed water-tightness and safety.
Rubber products made of EPDM rubber:
- EPDM O-rings
- porous EPDM cords (spongy)
- solid EPDM cords
- EPDM seals
- EPDM rubber sheets
- EPDM rubber sheets with a spacer
