U-Shaped Rubber Profiles

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
