One, the origin of the material monomer is different
1, silicone rubber
Fluoroelastomer is derived from the main chain or the side chain of the carbon atoms containing fluorine atoms on the synthetic polymer elastomer.
2. Fluoroelastomer
The introduction of phenyl can improve the resistance of silicone rubber to high and low temperatures, and the introduction of trifluoropropyl and cyano can improve the temperature and oil resistance of silicone rubber.
Two, the density is not the same
1, fluorine rubber (raw rubber) at about 1.8.
2, and silicone rubber in about 1.
Three, the degree of oil resistance is different
1, fluorine rubber oil resistance.
2, silicone is not oil resistant.
Four, different applications
1, fluoroelastomer is used in oil, corrosion and high temperature resistant environments, such as automobile engines, gearboxes, construction machinery.
2, silicone is used in high and low temperature environment, the actual use of electronics, food, medical machinery and equipment used more.
