Abstract

In this work hygrothermally decomposed crosslinked polyurethane (PUR) was mixed up to 20 phr in standard natural (NR) and nitrile rubber (NBR) recipes. Their curing (CV system) and mechanical behavior were studied. It was found that addition of decomposed PUR resulted in faster cure and reduced Mooney viscosity in NR compounds. The effect was however not prominent for a standard NBR recipe. Increasing PUR content in NR compounds resulted in a moderate increase in tensile strength, elongation at break, modulus at 300% elongation and tear strength. The opposite tendency was observed, however, for the NBR stocks. Both NR and NBR compounds showed an increase in compression set and abrasion with increasing PUR content.
