U-Shaped Rubber Profiles

20.08.2021

Benefits of Rubber Profiles

Rubber profiles offer flexibility, thermal insulation, and protection against UV, chemicals, and weather. Made from solid or cellular rubber, their shape (flat, round, U-shaped) depends on usage and supplier assortment.

Choosing the Right Material

Different rubbers serve different needs:

  • NBR for oil resistance

  • VMQ (silicone) for food-grade applications

  • EPDM for high-temperature environments

Materials’ hardness and density determine suitability. Coextruded profiles mix hardness levels or colors.

Solid vs Cellular Rubber Profiles

Solid rubber is uniform, often steel-reinforced, resistant to sharp edges, ideal for sliding seals in doors/windows. Cellular rubber has internal pores, offering sound insulation—used in automotive, agricultural machinery, and construction.

U-Profile Applications

Easy to install by sliding onto edges, U-profiles are mostly EPDM. They’re used in:

  • white goods (washing machines, dishwashers, fridges)

  • water installations and bathroom ceramics

  • industrial, construction, and automotive sectors (steam-resistant sealing)

  • door and window seals

Material Composition of U-Profiles

U-profiles are typically EPDM, NBR, SBR, sometimes silicone. EPDM leads due to:

  • chemical and UV resistance

  • high temperature, ozone, and aging resistance

  • flexibility and durability—common in door and window sealing
