| Abstract: |
| The effects of plasticizer types and dosage on the properties of hydrogenated nitrile rubber
（HNBR） were studied. The results showed that thet10 andt90 of HNBR compound using plasticizer TP-
95 were shorter，and the corresponding vulcanizates had good low-temperature resistance. The vulcanizates
using plasticizer DOS had high hardness，high tensile strength and good oil resistance. With the increase
of plasticizer dosage，the Mooney viscosities of HNBR compounds decreased significantly，and the low
temperature resistance was improved. When the dosage of plasticizer DOS was 20 phr，the HNBR vulcanizate
had good physical properties and oil resistance，as well as good low temperature resistance. |
