All well-known manufacturers of folding machines switched to polyurethane in the 1980s. This material has proven itself in continuous use and is still superior to other materials due to its properties. Material tests by recognized testing institutes show that the abrasion value of nitrile rubber (natural rubber) is 3 to 4 times higher than that of polyurethane. This means that rubber uses out up to 4 times faster.

For this reason, we only use polyurethane for our folding rollers.
