What are EPDM rubber profiles?

EPDM rubber profiles are extruded sealing and protection profiles manufactured from EPDM rubber (Ethylene Propylene Diene Monomer). They are widely used in applications where resistance to weathering, UV exposure, ozone and moisture is required.

Due to their long-term durability and elastic properties, EPDM rubber profiles are commonly applied in construction, automotive, marine and industrial environments.

Properties of EPDM rubber

EPDM is a synthetic elastomer known for its resistance to environmental influences. Key material characteristics include:

  • High resistance to UV radiation and ozone
  • Excellent weather and ageing resistance
  • Good flexibility across a wide temperature range
  • Water and steam resistance
  • Electrical insulation properties

EPDM is generally not suitable for prolonged exposure to oils, fuels or hydrocarbons.

Standard EPDM rubber extrusions

Many EPDM rubber profiles are produced as standard extrusions in commonly used shapes such as U-profiles, P-profiles, edge trims and sealing strips. These profiles are used in glazing systems, door and window seals, panel protection and industrial assemblies.

Standard shapes are available through our rubber extrusions range, covering widely applied profile geometries.

Custom EPDM rubber extrusions

For applications that require specific dimensions, tolerances or profile geometries, EPDM rubber profiles can be manufactured according to drawing or sample. Custom extrusion allows the profile shape, wall thickness and hardness (Shore A) to be adapted to the installation requirements.

Custom solutions are commonly used in façade systems, marine sealing, machinery enclosures and technical equipment. More complex geometries are typically produced via custom rubber extrusions, where compound selection and dimensional accuracy are aligned with the application.

EPDM compared to other rubber materials

Compared to elastomers such as NBR or natural rubber, EPDM offers superior resistance to weathering and ozone. For oil-resistant or fuel-exposed environments, alternative rubber compounds may be more appropriate.

The correct material selection depends on operating conditions, mechanical load and environmental exposure.
