Effect of the acrylonitrile content in nitrile-butadiene rubber on the relative residual deformation of vulcanizate

The paper presents the results of a study of rubbers based on butadiene-nitrile rubbers (NBR) grades BNKS-40 and BNKS-18. The influence of the content of acrylonitrile (NAC) on the rheological and physico-mechanical properties of vulcanizates has been evaluated. It is shown that the content of NAC i...

Description
Summary:The paper presents the results of a study of rubbers based on butadiene-nitrile rubbers (NBR) grades BNKS-40 and BNKS-18. The influence of the content of acrylonitrile (NAC) on the rheological and physico-mechanical properties of vulcanizates has been evaluated. It is shown that the content of NAC in the NBR composition significantly affects the relative residual compression deformation of the vulcanizate both under normal conditions and at elevated temperatures. The dependencies revealed in the work make it possible to make the correct choice of the rubber grade in the development of rubber resistant to compression deformation.
