氟橡胶（FKM）
Fluorine Rubber (FKM)
1、化学稳定性佳：氟橡胶具有高度的化学稳定性，是目前所有弹性体中耐介质性能最好的一种，
1. Chemical Stability: Fluorine rubber has high chemical stability, and is one of all elastic bodies with best medium resistance performance.
2、耐高温性优异：氟橡胶的耐高温性能和硅橡胶一样，是目前弹性体中最好的，250℃下可长期使用，300℃下短期使用，
2. Excellent High Temperature Resistance: The high temperature resistance performance of fluorine rubber is the same as that of the silicon rubber, thus the best among current elastic bodies. It can be used for a long time below 250℃ and can be used for a short time below 300℃.
3、耐老化性能好：氟橡胶具有极好的耐天候老化性能，耐臭氧性能。据报导，DuPont开发的VitonA在自然条件存放十年之后性能仍然令人满意，在臭氧浓度为0.01%的空气中经45天作用没有明显龟裂；
3. Good Aging resistance Performance: Fluorine rubber has excellent weather and aging resistance as well as the ozone resistance. It is reported that the VitonA developed by DuPont has satisfying performance after being stored for ten years under natural conditions, and there is no obvious cracking exposed to the air among which the ozone concentration is 0.01% for 45 days.

5、机械性能优良：氟橡胶具有优良的物理机械性能。26型氟橡胶的拉伸强度在10~20MPa之间，扯断伸长率在150~350%之间，抗撕裂强度在3~4KN/m之间。23型氟橡胶拉伸强度在15.0~25MPa之间，伸长率在200%~600%，抗撕裂强度在2~7MPa之间。
5. Fine Mechanical Performance: Fluorine rubber has fine physical and mechanical performance. The tensile strength of the 26-type fluorine rubber is between 10~20MPa, and the elongation at rupture is between 150~350%, with the tear resistance strength being between 3~4KN/m. The tensile strength of the 23-type fluorine rubber is between 15.0~25MPa, and the elongation at rupture is between 200%~600%, with the tear resistance strength being between 2~7MPa.
6、透气性小：氟橡胶对气体的溶解度比较大，但扩散速度却比较小，所以总体表现出来的透气性也小，
6. Air Permeability: Fluorine rubber has great solubility to gases, but small diffusion velocity, therefore, the overall air permeability displayed is also small.
7、低温性能：氟橡胶的低温性能不好，这是由于其本身的化学结构所致；
7. Low Temperature Performance: The low temperature performance of fluorine rubber is not very good, which can be attributed to its chemical constitution.
8、耐辐射性能： 氟橡胶的耐辐射性能是弹性体中比较差的一种。
8. Radiation Resistance Performance: The radiation resistance of fluorine rubber is the poorest among all elastic bodies.
