Quality of Keder Core

The quality of Keder core depends on the quality of the PVC composition. PVC is a rigid material mixed with a plasticizer to make it soft and flexible.


With the poor quality of the plasticizer, the core starts releasing oil on its surface and then slowly becomes brittle. Due to the oily surface, the core also starts slipping from the welded sleeve of the fabric.


Keder Max manufactures its core with properly tested and validated polymer composition. The high-grade PVC composition is equivalent to the one used for medical applications.
