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
