2008-3-21 · Elongation of Conveyor Belt. We use NN (nylon x nylon) belts at our sandwich belt high-angle conveyors. This is precisely because of the low elastic modulus which facilitates the tighter convex curves of the troughed belts. The elastic stretch is desirable, the permanent stretch is not but is worth it.
