| Abstract: |
| The applications of methylvinylphenyl polysiloxane rubber（MVPQ）with brand name of SE6660，SE6635 and SE5563U and the vulcanizer DCBP and DBPH in the aerospace field were comparatively studied. The results showed that the comprehensive properties of SE5563U MVPQ were better，and SE5563U MVPQ cured with DBPH had a high crosslinking density，good tear resistance，small compression set and brittleness temperature of － 110 ℃，which was very suitable for sealing materials of doors and windows of aerospace vehicle. |
