EPDM rubber sheet

EPDM rubber sheets are made from a synthetic elastomer with high resistance to weathering, ozone and UV radiation. They are suitable for applications where lasting elasticity and ageing stability are required.

In industrial use, EPDM sheets are frequently used as seals, protective layers or separating layers. The material remains dimensionally stable even under long-term outdoor weathering and shows consistent recovery behaviour.

Typical fields of application are mechanical and plant engineering, vehicle construction and technical sealing in outdoor areas. Compared with other rubber grades, the focus with EPDM is on environmental resistance and temperature tolerance, less on oil or fuel contact.

For related applications and alternative materials, the overview of rubber sheets for technical applications offers a structured classification by material and field of application.

Technical properties of EPDM rubber sheets

EPDM rubber sheets are made from ethylene-propylene-diene monomer and are preferably used in applications where weather resistance and lasting elasticity are required.

Mechanical and physical characteristics

• Material: ethylene-propylene-diene monomer (EPDM)
• Colour: black
• Hardness: 60 ± 5 Shore A
• Density: approx. 1.25 g/cm³
• Tensile strength: approx. 6 MPa
• Elongation at break: approx. 300 %

These characteristics enable use as a sealing, protective and damping material in industrial applications.

Resistances and functional properties

EPDM exhibits high resistance to ozone, UV radiation and weathering effects. The material is suitable for permanently stressed outdoor applications and retains its properties over long periods.

The usable temperature range is typically between -40 °C and +120 °C. Within this range, EPDM remains elastic and dimensionally stable.

EPDM shows good chemical resistance to diluted acids, alkalis and polar media. In addition, the material has good electrical insulation properties and is suitable for electrotechnical applications.

For applications with direct oil or fuel contact, alternative elastomers are more suitable.

For practical implementation, EPDM sheets are available as a precisely fitting rubber sheet cut to size.

Dimensions and cutting of EPDM rubber sheets

EPDM rubber sheets are available in different thicknesses and dimensions and are suitable for a wide range of technical applications. The choice of the right material thickness depends on the load, the desired elasticity and the intended field of application.

For industrial applications, EPDM sheets are frequently used as cut pieces in order to enable precise adaptation to components, sealing surfaces or machine components. Dimensionally accurate cut pieces support clean installation and reduce rework on site.

EPDM can be used both for simple rectangular cut pieces and for more complex contours. The material is therefore suitable for series applications as well as for one-off productions or prototypes.

Production is carried out as an individual rubber sheet cut to size, tailored to the respective technical requirements.

Fields of application of EPDM rubber sheets

EPDM rubber sheets are used wherever lasting elasticity, weather resistance and ageing stability are required. The material is suitable for industrial and commercial applications with static or slightly dynamic load.

Construction and building technology

In construction, EPDM is used as a sealing material for roofs, façades and window and door connections. The high UV and ozone resistance supports long-term use outdoors.

Mechanical and plant engineering

In mechanical and plant engineering, EPDM rubber sheets serve as seals, protective layers or separating layers. The elastic properties enable the compensation of manufacturing tolerances and reduce vibrations between components.

Vehicle and apparatus construction

EPDM is used in vehicle and apparatus construction for covers, protective mats and sealing applications where temperature and weather stability are relevant.

Electrical and energy technology

Thanks to its electrical insulation properties, EPDM is suitable for use as a protective and insulating material in technical housings and control cabinets.

For specific projects, EPDM rubber sheets can be implemented as a precisely fitting rubber sheet cut to size.

EPDM compared with other rubber materials

EPDM rubber sheets are used specifically when environmental resistance and ageing stability are the priority. Depending on the application, however, other elastomers may also be considered that cover other priorities.

EPDM is particularly suitable for applications with permanent outdoor exposure. Resistance to UV radiation, ozone and weathering is among the central material advantages. Typical fields of application lie in construction, in mechanical engineering and in technical sealing outdoors.

Other rubber materials are preferably used when media resistance to oils, greases or fuels is required or when mechanical loads are the priority. The material selection therefore always depends on the specific application environment, the ambient conditions and the functional requirements.

For projects in which EPDM is the suitable choice, the sheets can be implemented as a precisely fitting rubber sheet cut to size and adapted exactly to the respective application.

EPDM rubber sheets as a sealing material

EPDM rubber sheets are frequently used as a base material for technical seals. The material properties such as elasticity, weather resistance and ageing stability support reliable sealing in industrial and commercial applications.

Typical fields of application lie in construction, in mechanical and plant engineering and in technical sealing outdoors. Depending on the application, EPDM seals are designed as flat gaskets, strips or contour-accurate cut pieces.
