The main chain of (silicon rubber) silica gel is composed of silicon (- Si-O-Si). It has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistance. It has good electrical insulation. The tensile strength of rubber is worse than that of general rubber and it is not oil resistant. Service temperature: - 55 to 250 ℃.
Advantage:
Good elasticity and good compressibility
Good resistance to neutral solvents
Excellent heat resistance
Excellent cold resistance
Excellent resistance to ozone and oxide attack
Excellent electrical insulation
Good heat insulation and heat dissipation
Disadvantages:
It is not recommended to use in most concentrated solvents, oil products, concentrated acids and diluted sodium hydroxide.
Application fields:
It is suitable for high speed rotating seal and all kinds of food mechanical seal under high and low temperature.
