Silicone rubber has a great many variations and can be
compounded to meet any number of applications.
Silicone can be compounded to have tensile in the area
of 1500 PSI and tear up to 200 lbs; low compression set
and good resilience; moderate solvent resistance;
excellent heat resistance; good release characteristics;
extreme low temperature properties; and can be highly
resistant to oxidation and ozone attack. Silicone is
generally attacked by most concentrated solvents, oils,
concentrated acids and dilute sodium hydroxide.
