AN INFLUENCE OF FILLERS ON ABRASIVE WEAR OF SEGMENTED POLYURETHANEURA
As an object of research, we have chosen a well-known elastic polymer material – polyetherurethane urea SKU-PFL, which is a typical segmented block copolymer. Powdered microdispersed fillers capable to improve wear resistant such as calcium stearate and molybdenum disulfide were added to this material at the manufacturing stage in varying amounts (up to 1.5% by weight). The found level of the optimal filler concentration for the investigated elastomers in the region close to 0.5 wt% makes it possible to consider calcium stearate and molybdenum disulfide as not only effective but also economical components of promising wear-resistant polymeric materials.
