| Abstract: | Studied about the heat resistant process of the fluoroelastomer products.It was founded out to fit the heat resistant process of the fluoroelastomer by a lot of tests and measuring the physical properties tests(tensile strength,elongation at break and hardness).It was analyzed and studied that the milling affects the physical properties,vulcanized temperature and the time affects tensile strength and elongation,relationship between the hardnes and the dosage of the assistant and the aging affects the hardness change up and down.The results showed that the temperature of resistance hot had researched 275?℃,which was superior to the present level of fluoroelastomer products (250?℃)at home. |
