| Abstract: |
| The preparation process and performance of medical latex balloon were studied in order to solve the problem of the balloon deviation problem.The results showed that，by using pre-vulcanization natural latex with a pre-vulcanization degree between three-end and four-beginning，along with alcohol-clay coagulant，employing a reasonable automatic impregnation process，filtering for 6 minutes at 65 ℃，and drying vulcanization for 30 minutes at 100℃ with mold，the latex balloon could be produced with high sphericity positive ratio，excellent physical properties and superior visual quality，which could meet the domestic market demand. |
