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 BGK ENDLESS BELTS.
P-5100
THE NON-REINFORCED POLYURETHANE BELT
Given its high elasticity and good preload force, the P-5100 belt is ideal as a drive or conveyor belt for fixed axle distances. Its surface is ground on both sides, at 0.9 mm very thin and can therefore also be used for small pulley diameters of only 8 mm.
