Some of the major properties of silicone which enables its wide usage are:
Non-reactivity, stability and resistance towards environment and wide temperature range.
Easy to manufacture and shape for variety of purposes. High elongation, creep, cyclic flexing, tear strength, compression strength, dielectric strength, thermal conductivity and free resistance at extreme temperature range.
It is resistant and does not react to most of the chemicals. High inertness enabling its use in medical equipments.
The above mentioned are just the industries which use silicone rubber sheets. However, the type of usage of these sheets in the above mentioned industries are given below:
