| Abstract: |
| The properties of natural rubber latex from RRIM600 with 3，13，20，24 and 28 tapping years were investigated，such as particle size of natural rubber latex，properties of raw rubber，curing characteristics of rubber compound and physical properties of the vulcanizates.The results showed that the average particle size of natural rubber latex from 28 tapping year rubber trees was the smallest and its particle size distribution had a narrow distribution range.Plastic initial value and Mooney viscosity of raw rubber from 20 tapping year rubber trees were higher.The tensile strength and tear strength of vulcanizate from 20 and 28 tapping year rubber trees were higher. |
