Influence of the changes of raw rubber and plasticizing system on the
mechanical properties of oil and cold resistance of NBR

Sun Zhenhao, Wang Chenyang, Deng Tao*
Abstract: In this paper, the influence of NBR system on the oil resistance, cold resistance and mechanical
properties of vulcanizates was studied by changing the plasticizing system and using NV7030 rubber-plastic
alloy together. Studies have shown that the performance of the vulcanized rubber after the combined use
of plasticizers DOS and DOA is slightly better than that of the vulcanized rubber with a single plasticizer, and it
has excellent cold resistance. After the combined use of rubber and plastic alloys, the mechanical properties
decrease, but the oil resistance at room temperature does not change significantly, and the cold resistance
decreases slightly, but it still has application value.
Key words: Nitrile rubber (NBR); oil resistance; cold resistance
(R-03)
