Excellent high temperature resistance

The high temperature resistance of fluorine rubber is the same as that of silicone rubber, which can be said to be a good elastomer at present. 26-41 fluorine glue can be used for a long time at 250℃, and for a short time at 300℃; 246 fluorine adhesive heat better than 26-41. The physical properties of 26-41 after air thermal aging at 300℃×100 hours are similar to those of 246 after air thermal aging at 300℃×100 hours. The elongation at break can be maintained at about 100%, and the hardness is 90~95 degrees. Type 246 maintains good elasticity after 16 hours of aging in hot air at 350℃, and good elasticity after 110 minutes of aging in hot air at 400℃. After 110 minutes of aging in hot air at 400℃, the elongation of rubber material containing spray carbon black, hot cracking carbon black or carbon fiber increases by about 1/2~1/3. Strength decreased about 1/2, still maintain good elasticity. Type 23-11 fluorine adhesive can be used for a long time at 200℃ and for a short time at 250℃. Discontinuous at 600°F(315 ° C);

Excellent aging resistance
Fluorine rubber has good weather aging resistance and ozone resistance. After 10 years of natural storage, the properties are still satisfactory, and there is no obvious cracking after 45 days in the air with ozone concentration of %. Type 23 fluorine rubber is also very good at weathering resistance and ozone resistance.

Vacuum performance is very good
Type 26 fluorine rubber has good vacuum properties. The vacuum release rate of 246 fluorine rubber base formula is only 37×10-6 NODL/s. Centimeters 2. Type 246 fluorine rubber has been successfully applied under vacuum conditions of 10-9???? Attached??

Excellent mechanical properties

Fluorine rubber has excellent physical and mechanical properties. 26 type fluorine rubber generally with a strong force between 10~20MPa, elongation at break between 150~350%, tear strength in 3~4KN/m. The strength of type 23 fluorine rubber rubber is between 25MPa, elongation rate is 200%~600%, tear strength is between 2~7MPa. Generally, the compression deformation of fluorine rubber at high temperature is large, but if compared with the same conditions, such as the compression deformation of the same time at 150℃, butyl and chloroprene rubber are larger than 26 fluorine rubber, 26 fluorine rubber at 200℃×24 hours of compression deformation is equivalent to the compression deformation of butyl rubber at 150℃×24 hours.
