Silicone rubber is physioloyically insert,thus making it preferred choice of medical,pharmaceutical and food
Silicone rubber have comparatively low mechanical properties,tensile strength,elongation and tear strength.
Silicone rubber is excellent resistance to oil and hydrocarbon products is fairly limited and similar to that of chloroprene rubbers.Reasonable resistance to a whole range of general chemical products,but acids,alkalis,esters and kerosene should be avoided.
Silicone rubber is excellet resistance to heat,at 200 ℃and +220℃intermottent.It remains flexible at low temperatures of -70℃.
Silicone rubber is good electrical insulation properties.
Silicone rubber is resistant to ultra-violet light,ozone and weathering.
