Some of the most useful properties of silicone include:

1.Good electrical insulation.

2.Thermal stability (constancy of properties over a wide operating range of −100 to 250 °C).

3.Though not a hydrophobe, the ability to repel water and form watertight seals.

4.Excellent resistance to oxygen, ozone and UV light (sunlight).

5.Does not stick.

6.Low chemical reactivity.

7.Low toxicity, but does not support microbiological growth.

8.High gas permeability
