What are the high- and low-temperature properties of Fluorosilicone?
Fluorosilicone combines the good high- and low-temperature properties of silicone.
How does Fluorosilicone's fuel and oil resistance compare to other rubbers?
Fluorosilicone has limited fuel and oil resistance compared to Fluorocarbon rubbers.
What chemical properties does Fluorosilicone share with fluorinated organic elastomers?
Fluorosilicone provides chemical properties similar to those of fluorinated organic elastomers, including excellent resistance to hydrocarbon fuels, petroleum oils, and silicone fluids.
In what temperature range can Fluorosilicone elastomers operate?
Fluorosilicone elastomers can operate in a temperature range of -70°F to 400°F (-57°C to 205°C).
Where are many applications for fluorosilicones found?
Many applications for fluorosilicones are found in synthetic oils, gasoline, and extended fuels due to their superior low temperature performance compared to Fluorocarbon rubbers.
How does Fluorosilicone differ from standard silicone?
Fluorosilicone offers improved fuel and mineral oil resistance and remains stable in high temperatures and harsh weather environments. However, it has poorer hot air resistance compared to standard silicone.
What chemical groups are present in fluorosilicone that enhance its chemical resistance?
Fluorosilicone contains trifluoropropyl groups that enhance its chemical resistance to non-polar solvents, fuels, oils, acids, and alkaline chemicals.
What are the recommended applications for fluorosilicones?
Due to their relatively low tear strength, high friction, and limited abrasion resistance, fluorosilicones are generally recommended for static applications only. However, there are also fluorosilicone compounds available with high tear strength and improved resistance to compression set.
How does the shrinkage rate of fluorosilicone compounds differ from normal?
Many fluorosilicone compounds have a higher than normal shrinkage rate.
Are production molds for fluorosilicone products the same as molds for nitrile?
No, production molds for fluorosilicone products are often different from molds for nitrile due to the higher shrinkage rate of fluorosilicones.
