Banner PVC Keder for Sports Event Tent accessories

What is Keder?

Keder consists of two parts: a core and fabric. The core is made from extruded PVC, or another elastic material, to allow flexibility. The core is then wrapped in Keder fabric, which has exposed fibers on the outside to allow the Keder to easily slide into an extrusion with a luff groove – keder track. It has coating on the inside, to ensure proper adhesion during welding. For maximum strength, there is a Double Coated Keder available

The method for welding keder to fabric depends on the style that is being used. Double flap keder is generally welded using a radio-frequency welder due the fact that, three layers of fabric are welded at the same time.
