Description:

Silicones are elastomers made from silicone, oxygen, hydrogen and carbon. Silicones are used in the medical and food industry because they do not have any odor or taste.

Advantages:

Resistant to oxygen, ozone, UV light, mineral and vegetable oils, diluted salt solutions, engine and transmission oil, brake fluids (non petroleum base), fire resistant hydraulic fluid, high molecular weight chlorinated aromatic hydrocarbons. Good flexibility and compression set.

Disadvantages:

Cannot be used in acids, EP fluids, fuels, gear oils, ketones and benzene. Should not be used in dynamic applications due to it’s low tensile strength, poor wear and tear strength.
