| Abstract: |
| The influence of aging time at 200 ℃ on the heat aging resistance and structure of fluoroether rubber was investigated.The results showed that，fluoroether rubber kept good physical properties after aging for 22 days.As the aging time prolonged， the glass transition temperature and storage modulus of fluoroether rubber at the temperature above -50 ℃ were not changed，but loss factor increased slightly.Fluoroether rubber was suitable for sealing material used at the temperature above -50 ℃. |
