1.Comparison of flame retardancy: the flame retardancy of fluorine rubber is higher than that of silicone rubber, while the flame retardancy of blends is close to that of silicone rubber as continuous phase in blends.
2.Degradation temperature (Td) comparison: the explant temperature of blend was higher than that of single rubber.The thermal behavior of the blends is determined by the fluorine rubber phase, and the thermal stability of the blends is similar to that of fluorine rubber.Because of the instability of SiF4, the residues of the blends after thermal degradation were low.
3.Fluorine rubber has better oil resistance than silicone rubber.In terms of retention rate of mechanical properties, the tensile strength and elongation at break of the blend are close to that of fluorine rubber, and the mass and hardness of the blend are between each single rubber.
4.The blend of silicone rubber and fluorine rubber can be the substitute of fluorine silicone rubber.
The cinereus solid, the relative density 0.986-1.00, dissolve in the benzene, the acetone, the ethanoic acid, the ethyl acetate, the dichloroethane alkane and the toluene, does not dissolve in the water
