| Abstract: | The aging resistances of natural rubber （NR） vulcanizates from two tapping system of rubber trees were investigated by the conventional method of hot-air aging combined with thermogravimetry （TG） ,differential scanning calorimetry （DSC） and rubber processing analyzer （RPA）. The results showed that the aging-resistance of NR vulcanizate from tapping system A is better than that of tapping system B. |
