The mechanical properties of silicone elastomers at room temperature are inferior to those of other elastomers.Silicone elastomers are unaffected by oxygen and ozone on natural ageing. Because of their water-repellency, silicone elastomers are not seriously affected by aqueous solutions of most chemical reagents.They are attacked by strong acids and alkalis. General purpose elastomers are swollen by aliphatic, aromatic and chlorinated hydrocarbons but much improved resistance is shown by nitrile- and fluorine-containing silicones. In general, room temperature- cured materials have lower solvent resistance.
