What are crown profiles?

Crown profiles are seals with a characteristic crown shape that are made from the elastomer EPDM (ethylene propylene diene rubber). Their special shape enables optimal adaptation to uneven surfaces and thus ensures reliable sealing. EPDM is characterized by its excellent weather resistance, ageing resistance and flexibility, which makes crown profiles made of this material a durable and effective solution.

Properties of EPDM crown profiles

EPDM crown profiles have a number of properties that make them an ideal choice for a variety of applications:

Thermal properties:

Thermal insulation: EPDM is a good thermal insulator and minimizes heat loss through windows and doors. This contributes to a pleasant indoor climate and reduced heating costs.
Cold resistance: EPDM retains its flexibility even at low temperatures, ensuring its sealing function even in winter.
Heat resistance: EPDM is resistant to heat exposure up to a certain temperature, which also makes it suitable for use in warmer climates.

Mechanical properties:

Flexibility: EPDM is a very flexible material, which allows crown profiles to adapt to uneven surfaces and ensure optimal sealing.
Pressure resistance: EPDM crown profiles are resistant to pressure loads and retain their shape even under prolonged stress.
Tensile strength: EPDM has good tensile strength, which increases the longevity of the profiles.
UV resistance: EPDM is resistant to UV radiation and retains its properties even after long-term exposure to sunlight.
Ozone resistance: EPDM is resistant to ozone and other environmental influences, which extends the service life of the profiles.

Acoustic properties:

Sound insulation: EPDM crown profiles contribute to sound insulation by reducing the passage of sound through windows and doors. This ensures a quieter living and working atmosphere.

Crown profiles in use – diverse applications in all areas

Thanks to their versatile properties, EPDM crown profiles are used in a wide variety of industries:

Construction: Sealing of windows, doors, facades, winter gardens and roof structures
Vehicle construction: Sealing of doors, windows and sunroofs
Mechanical engineering: Sealing of housings, flaps and doors
Shipbuilding: Sealing of hatches, doors and windows
Electrical engineering: Sealing of control cabinets and electronic housings
