Abstract
The subject of the study was rubber based on partially and fully hydrogenated butadiene-nitrile rubbers (HNBR) Therban АТ 5065 VP and Therban АТ 5005 VP, taken in the ratios 100:0, 80:20, 70:30, 60:40, 50:50 accordingly. The purpose of the study was to evaluate the technical resource of RKO operation by predicting changes in properties of rubbers during thermal aging in air and in М-14В2 engine oil at elevated temperatures in accordance with State Standards and methods developed at FRPC “Progress”. Aggressive environment and high temperatures thermal aging of elastomers based on HBNR are described. The performance of rubbers was evaluated by predicting changes of relative elongation near to end of service life product to State Standards and “Progress” recommendations. It is found that elastomer with 50:50 HNBR Therban АТ 5065 VP and Therban АТ 5005 VP content proved itself as most thermally stable and has the longest service life possible.
