SILICONE (SI) Polysiloxane
Advantages:
Outstanding resistance to high heat; excellent flexibility at low
temperatures; low compression set; very good electrical insulation;
excellent resistance to weather, ozone, sunlight and oxidation; superior
color stability.
Limitations: Poor resistance to abrasion, tear,
and cut growth; low tensile strength; inferior resistance to oil,
gasoline, and solvents; poor resistance to alkalis and acids.
Comment:
The most outstanding feature of silicone is its ability to retain
rubbery properties through extremes in temperature. It is the most heat
resisting elastomer in the market today and the most flexible at low
temperatures. Service temperatures range from -150 to 500F. Silicone
generally does not have high tensile strength, but much of the strength
it does have can be retained at very high temperatures. Because
silicone is relatively expensive, it is not normally used unless extreme
temperature resistance is essential.
