EPDM
remarkable against many chemicals
and all environmental influences
Ethylene-propylene-diene rubber
Ethylene propylene diene rubber (EPDM) is characterized by a remarkable combination of
material properties. This includes impressive chemical resistance to diluted
Acids, alkalis, solvents and hydraulic fluids. At the same time, its elasticity and flexibility
permanent deformation under load while maintaining the dimensional stability of the material.
Above all but was EPDM developed to permanently withstand all environmental influences.
​
Chemical structure
​
EPDM is a terpolymer created by the polymerization of ethylene, propylene and a diene.
The addition of the diene enables the formation of sulfur-crosslinkable double bonds in the side chains of the polymer.
This structural aspect significantly influences the material properties and crosslinking behavior of EPDM.

​
The unique chemical structure gives EPDM a combination of flexibility, strength and durability, which makes it indispensable in various industrial sectors. ​It is resistant to weather influences, ozone, UV, aging-related changes and many chemicals. EPDM is used in various industrial applications where a combination of elasticity, weather resistance and chemical resistance is required. flexibility EPDM is characterized by a high level of flexibility, which makes it particularly adaptable for various applications. This flexibility is retained even at low temperatures. ​ Tear resistance EPDM has good tear strength, meaning it is resistant to cracks and mechanical stress. This makes it particularly suitable for applications where high stress may occur. ​ Wear resistance Due to its chemical structure and composition, EPDM shows excellent wear resistance. It retains its integrity and surface quality even with repeated use. density The density of EPDM is in the range of approximately 0.85 to 0.87 g/cm³. This moderate density enables good processability and at the same time makes the material light and manageable. Insulation properties EPDM offers good electrical insulation properties, which is why it is often used in the electrical industry to produce cable insulation. Weather resistance EPDM is extremely weather-resistant and shows high resistance to UV radiation and ozone. This feature makes it ideal for outdoor use. Chemical resistance EPDM resists many chemicals, acids and bases, making it versatile, including in environments with chemical exposure. Temperature resistance EPDM retains its flexibility and elasticity over a wide temperature range of approximately -70°C to +150°C, allowing it to be used in various climates and applications. Water vapor resistance EPDM has a low water vapor permeability, which makes it suitable for sealing applications, particularly water-resistant seals.
Material hardness and coloring
EPDM is available in different hardness grades, ranging from soft (20 Shore A) to harder types
(over 90 Shore A) is enough. The material hardness can be adjusted depending on the requirements of the application. In terms of color schemes, EPDM is usually available in black or light shades such as white or light grey.available.
Industries and applications
​
EPDM is widely used in various industries due to its unique material properties.
In the automotive sector it is used for hoses, seals, door profiles and membranes.
In construction, EPDM is used as a high-quality material for waterproofing membranes, flat roof sealing or films.
In addition, it is used in steel hydraulic engineering for docking , lock sealing or
the industry for conveyor belts, expansion joints and flexible piping.
​
Automotive industry EPDM is used for gaskets, door and window seals, hoses, O-rings and other sealing components in vehicles. ​ Construction industry EPDM is used in roof seals, window seals, facade profiles and other building elements. Electrical industry Due to its good electrical insulation properties, EPDM is used for cable insulation and seals in electrical applications. domestic appliances EPDM is used in gaskets and sealing rings of household appliances, especially when it comes to weather resistance and durability. ​ Water technology Due to its resistance to water vapor and various weather influences, EPDM is used for seals and membranes in water applications.
The outstanding material properties, the resistance to environmental influencesversatile Hardness levels
and the wide range of applications make ethylene propylene diene rubber a key material in various industries. Continuous research and development in this area contributes to
to further expand the areas of application of EPDM and optimize its performance.
