What is the heat resistance of food grade fluoroplastic oil seals?

What is the heat resistance of food grade fluoroplastic oil seals? Fluorine rubber filler has good heat resistance, it can work for a long time at 200~250℃, and also work for a short time below 300℃. With the increase of temperature, the tensile strength and strength of fluorine rubber decreased significantly. The variation characteristics of tensile strength and strength are as follows: 150 °C decreases rapidly with the increase of temperature; in the middle of 150-260 °C, with the increase of temperature, the downward trend becomes slower. The food-grade fluorine rubber oil seal guarantees that the elastic temperature is limited to -15~-20℃. With the decrease of temperature, the tensile strength increases and becomes tough at low temperature. The ductility temperature of MM is -30℃; the temperature of thin thickness is 1.87MM and the temperature is -45℃; the temperature of thin 0.63MM is -53℃; the thickness of 0.25MM is -69℃. Generally, the application temperature of fluorine rubber can be slightly lower than the ductility temperature. Fluorine rubber has excellent corrosion resistance. to the potion. . Light fuel oils are different. Grease has good analytical stability and is good for most substances. Nitrogen oxides. Benzene. Xylene has excellent corrosion resistance. Fluorine rubber is used for sealing under high temperature, which is characterized by small deformation. Therefore, the application of binaural type fluorine rubber is very common, and it is inseparable from the improvement of reducing deformation. Fluorine rubber has excellent aging resistance and ozone resistance, and the effect of VITONA is still satisfactory after 10 years of natural storage. In the air with a carbon dioxide concentration of 0.01MM, the effect of 45 days has no obvious rupture.
