Physical and mechanical properties of compounded hydroxylated natural rubber

In this study, oil resistance properties, tensile strength and hardness properties of compounded hydroxylated Natural rubber (OONR) were evaluated. Oil and oxidation natural rubber (OONR) exhibited shorter cure time compared to the SMR-L and EPDM and recorded better crosslinks density. The performance of OONR clearly dominated the unmodified NR in terms of swelling to hydrocarbon oils and non-polar solvents. The OONR also depicted an increasing trend in hardness compared to the unmodified NR. However, the tensile strength of OONR vulcanizate was drastically decreased compared to SMR-L and EPDM compounded rubber.
