Rubber Extruded Profiles

Rubber extruded profiles are continuous rubber components produced by pushing (or drawing) an uncured rubber compound through a shaped die so that the resulting product has a constant cross-section (the “profile”). 

Profiles (Shapes & Cross-Sections)

• They can come in simple shapes, such as U-channels, T-profiles, P-profiles, L-profiles, D-profiles, and E-strips, among others. 
• They can also be more complex, custom cross-sections designed to fit a specific function, e.g., glazing seals, door seals, special trim. 
• We can also produce rubber, fabric, and metal-composite extruded products by using the multi-head composite extrusion method.

Post-processing may include cutting, splicing (for closed loops), joining corners, punching holes, and assembling with other parts. 

Materials

Rubber extruded profiles can be made from a wide variety of elastomeric materials, depending on the application, including:

• NR (Natural Rubber)
• SBR (Styrene-Butadiene Rubber)
• NBR (Nitrile Rubber)
• EPDM (Ethylene-Propylene-Diene Monomer)
• CR (Chloroprene)
• Silicone Rubber
• FKM / Fluoroelastomers
• Thermoplastic Elastomers (TPE) or TPV (Thermoplastic Vulcanizates) in some cases. 
•  Almost all materials can be formed into a foamed sponge.

Application Examples

• Window/door seals: U or P profiles in EPDM used to seal metal/glass frames, resist weather, and UV. 
• Automotive trim/sealing: Custom profile shapes to fit door edges, hatches, cabins, in materials resistant to oil/heat. 
• Industrial equipment seals: Profiles that seal equipment enclosures, vibration isolation strips, and edge guards on cabinets.
• Building construction: Rubber extrusions for facades, glazing channels, and expansion joints. 
• Transportation/shipping: Profiles for protective edging, shock absorption, cushion strips on metal frames.

Joining/splicing can be a weak point—loops or closed shapes may require a vulcanised joint rather than a simple adhesive splice. 
Extrusion is usually economical for continuous lengths and moderate volumes, but for very small volumes or very complex shapes might cost more.
