The Effect of Multifunctional Additive on Dynamic and Physical Properties of Natural Rubber Gum Compounds

摘要

The paper reports the effect of multifunctional additive(MFA)on dynamic and physical properties of natural rubber gum compounds.As the MFA level increased,the maximum elastic torque (S'@MH) increased whereas the minimum elastic torque (S'@ML) decreased.Compared to the control compound (without MFA),the incorporation of MFA significantly reduced the viscous torque(S''@MH) and tan #delta# @MH especially below level of 2 phr.It was also found that to obtain better physical properties viz.tensile strength,tensile modulus and tear strength,the use of MFA at 2 phr is recommended.
