Functional Properties of Elastomers Based on Butadiene-Nitrile Rubbers

Abstract

In this article Therban AT 5065 VP, Therban AT 5005 VP - HBNR elastomers of different unsaturation degrees and their combined compositions research results (using optical and atomic force microscopy, DSC, DMA) are described. With these results structure and functional properties operational data of nitrile elastomers was obtained with no need of durable tests under different temperatures. It was found out that filler dispersion rises from 61.8 to 90.5 % and decomposition temperature grows from 261.9 to 275.3 °C while Therban AT 5005 VP share is increased from 20 to 50 weight parts. It is shown that elastomers with rubber ratio of 50:50 within temperature range from minus 30 to plus 150 °C have the lowest elasticity coefficient (from 311 to 1.6 MPa) and mechanical loss tangent (0.20) at the end of the test.
