SPRINTA PU endless belts are produced without any seam or splice. They are made of polyurethane coatings. Since there are no seams or splices, SPRINTA is optimal for diverse application possibilities in plant and machine construction. There are endless possibilities: in view of the possible combination of different base materials and coatings as well as further shaping by milling, punching, grooving and contouring, SPRINTA endless belts can be used in power transmission tasks or as conveyor belts.

Polyurethane, PU or PUR in short, is a very versatile plastic. Depending on the production process, it can be brittle and hard or also soft and elastic. It is therefore used as an all-rounder in many products which define our everyday lives.

The characteristics of PU from elastic to rigid are not least defined by the number of cells in the polyurethane. In case of a foam structure, PU is extremely abrasion resistant and is therefore used, for example, as protective coating in pipes or for transporting bulk goods. If its structure is closed and compact, however, it can also be used for food applications. Another advantage of PU in this case is that it contains no plasticizers as opposed to the otherwise frequently-used PVC. Even under extreme weather conditions and strong UV radiation, polyurethane has good ageing stability, good resilience under reversed flexing stresses, and is easy to clean – ideal prerequisites for its use as coating on high-quality SPRINTA endless belts.
