Silicon is one of the most abundant elements in the Earth's crust. It is a non-metallic element, having the atomic number 14. Siloxanes are chemical compounds composed of oxygen and silicon. Silicone basically refers to any of the classes of siloxanes. Most of us are aware of the fact that the binding energy of C-C bond is about 355 KJ/mol. However, with a value higher than that for C-C bond, silicones are stronger as compared to other polymers. This compound has a linked-chain structure. Silicone rubber exists in the liquid form. It needs to be converted into a solid in order to use it. In order to solidify this compound, it must be vulcanized, catalyzed, or cured. Given below are two processes that can be used for the same. Platinum-based System - This method uses platinum as a catalyst. The compound used in this process is vinyl and hydride siloxane polymer. This results in the formation of a bridge between the reactant and the catalyst. This system can also be called an addition system. Its advantages are that, the product is non-deformable, stable, and possesses a good grade of rubber. It also offers high resistance to high temperatures. Tin-based System - Alkoxy cross-linker on undergoing hydrolysis has a hydroxyl group remaining. This hydroxyl group then reacts with another group (belonging to the polymer) of the same type in a condensation reaction. This process happens at its own pace at room temperature. This method can also be termed as RTV, which is the short form for 'Room Temperature Vulcanizing'. Be it extremely high or low temperatures, silicone rubber is very stable as compared to organic rubbers. Its ability to resist most fluids makes it apt for meeting diverse needs.
