What Is Keder Fabric?
Keder fabric is a reinforced PVC coated textile used as the connection edge between fabric structures and aluminum profiles. The fabric is folded around a cord (PVC or polyester core) to create a strong sliding bead that fits into a keder rail, enabling tensioned and secure installation.
DERFLEX keder material features:
- High-tenacity polyester base fabric
- PVC coating for UV, mildew, flame and abrasion resistance
- Excellent welding compatibility (HF welding & hot air welding)
- Smooth sliding surface for track/rail installation
- Various weights from 300gsm to 900gsm
This makes keder fabric widely used in tents, truck tarps, industrial curtain systems, advertising frames, and modular temporary structures.
Main Features of DERFLEX PVC Keder Fabric
1. High Strength Polyester Base Cloth
We use industrial-grade high-tenacity polyester yarn to ensure long-term tension performance. The fabric maintains shape even under extreme outdoor pulling forces.
2. Excellent Weldability
Compatible with:
- Hot air welding
- High-frequency welding
- Hot wedge welding
The weld strength is equal to or even higher than fabric tensile strength.
3. UV and Weather Resistant
PVC coating is formulated with anti-UV components, ensuring extended durability in harsh sunlight and frequent installation cycles.
4. Optional Flame Retardant Grades
- B1
- M2
- NFP92-507
- NFPA701
5. Smooth Sliding Surface
Keder surfaces are finished with a low-friction coating to allow smooth insertion into aluminum tracks without deformation.
6. Multiple Colors & Custom Widths
Standard colors: white, grey, black. Custom colors available for branding or industrial specifications.
