Precision-Made. Performance-Tested. Built to Last.
At Elplasto Innovations, we specialize in the production of high-quality EPDM (Ethylene Propylene Diene Monomer) rubber profiles using advanced Continuous Vulcanization (CV) line technology. With in-house capability to produce both solid and sponge profiles, we deliver reliable sealing, insulation, and vibration control solutions for diverse industrial needs.
Our CV Line setup enables fast production, tight dimensional tolerances, and superior physical performance — ensuring your rubber profiles are ready to meet demanding real-world conditions.

Why Our EPDM Extrusions Stand Out
Advanced CV Line Production
Unlike traditional hot-air extrusion, our CV Line uses microwave, hot-air systems for inline curing. This ensures:
- Smooth, consistent surface finishes
- Enhanced tensile strength and elasticity
- Improved compression recovery
Custom Sizes Up to 100mm
We can extrude profiles with cross-sectional widths up to 100mm, covering both small, intricate designs and larger industrial sealing profiles.
Solid & Sponge Variants
Choose from:
- Solid EPDM profiles for robust sealing, structural support, and vibration dampening
- Sponge EPDM profiles for compressible, lightweight sealing where flexibility is key
Engineered Accuracy
Our extrusion process is backed by automated controls, inline inspection, and an in-house R&D team that ensures your designs are precisely manufactured every time.
Profile Types – Custom and Standard Shapes
We offer a wide range of standard and fully custom extrusion shapes, including:
- Simple Sections
- Round, Square, Rectangular, Flat Strips
- Tube & Cord profiles
- Specialty Seals
- D-shape, P-shape, E-shape, T-seal, L-seal
- Bulb seals, Lip seals, Hollow sections
- U-channels & Edge Protectors
- For glass, sheet metal, panel edges, and doors
- Glazing Gaskets & Rubber Beads
- Ideal for window systems, curtain walls, and partitions
- Custom Cross-Sections
- Manufactured from your CAD drawings, physical samples, or application sketches
