What is Medical Grade Silicone Rubber?

Medical grade silicone rubber is a kind of food grade silicone rubber. It is safely used in contact with living tissue, a characteristic called biocompatibility.   The application of medical grade silicone rubber: 1.medical devices such as bandages, feeding tubes, and medical implants 2.menstrual cups 3.barrier contraceptives 4.a variety of purposes in medicine 5.medical tubing in devices such as catheters and in seals 6.Many implanted medical devices contain silicone components, including pacemakers and artificial joints 7.cosmetic and reconstructive surgery   Silicones are polymers with a backbone made from a chain of alternating silicon and oxygen atoms, with each silicon  atom bonded to the oxygen atoms immediately before and after it in the chain and vice versa for each oxygen atom. Each silicon atom is also bonded to two organic side groups containing carbon, hydrogen, and in some cases other elements as well. Some silicone polymers have side groups and are able to bond with more than one silicon atom, creating even larger molecules composed of multiple linked chains. Silicones vary in their physical and chemical properties and in their suitability for medical use, according to their composition and structure.
