Silicone is a meterial or better say a mixture of many elements which has a wide use nowadays. Its use can be found in medicine as well as technology.


Silicones are inert, synthetic compounds with a variety of forms and uses. Typically heat-resistant and rubber-like, they are used in sealants, adhesives, lubricants, medical applications (e.g., breast implants), cookware, and insulation. Silicones are polymers that include silicon together with carbon, hydrogen, oxygen, and sometimes other chemical elements. Some common forms include silicone oil, silicone grease, silicone rubber, and silicone resin. [1]

Silicone is any of a group of silicon compounds in solid, liquid, or gel form, characterized by wide-range thermal stability, high lubricity, extreme water repellence, and physiological inertness and used in many medical products, including surgical implants and dental impression materials.
Silicone is any of a large group of inert polymers. Silicones are water-repellent and stable at high temperature. They are useful in medicine as adhesives, lubricants, and sealants. They are used in glass chromatography and in coating of glassware for blood collection because they help reduce platelet loss. They are also used as a substitute for rubber, especially in prosthetic devices. Elastomeric silicone, or silicon rubber, is biologically inert.
Silicone-gel breast implant is a type of implant used in reconstructive surgery of the breast and made with synthetic polymers. The implants have been associated with adverse effects on the immune system as well as distorted and painful breasts caused by leakage of the silicone into surrounding tissues. However, a number of statistical studies have not established such a cause-and-effect relationship. [2]

Medical grade silicones are silicones tested for biocompatibility and are appropriate to be used for medical applications. In the United States, the Food and Drug Administration (FDA) regulates materials implanted into the body. Medical grade silicones are generally grouped into three categories: non implantable, short term implantable, and long-term implantable. Materials approved as USP Class V and VI can be considered medical grade. Most medical grade silicones are at least Class VI certified. Silicone suppliers and some silicone prototyping companies provide guidelines for material use . [3]

Silicone is a heat and water resistant compound found in many products used in everyday life. Some of the most common uses for silicone are:

• Water tight containers: Aquariums and other enclosures that have joints such as shower stalls use a thin bead of silicone to seal the joint.
• Tile, faucet, or other pipe joints: Water pipes, faucets, and counter joints, and tiles are usually sealed with silicone to prevent leaks.
• Automobile Lubricant: Because of its high temperature tolerance silicone is used in brake lubricants in automobiles, as a coating on spark plug wires to insure stay sparks do not ignite, and sheet silicone is often used in making various automotive parts especially surrounding engine or other heated areas.
• Cookware Coatings: A thin base of silicone coating cookware gives it a long durability and non-stick benefits.
• Dry Cleaning Solutions: Silicone is an environmentally friendly chemical that can be used as a dry cleaning solvent.
• Electronics Casings: Silicone is often employed in making casings for various electronic devices due to its ability to shield electrical shocks, vibrations, and radiation.
• Flame Retardants: Silicone bases in materials used in construction can provide excellent fire breaks preventing the spread of flames. It is often used in the manufacture of various materials used to make clothing, furnishings, and even runs in order to give items a fire retardant finish.
• Personal and Common Lubricants: Silicone bases are used in many common lubricants from bike chain oils, spray on lubricants for locks or bolts, and even human sexual lubricants, and lubricants used for medical purposes such as surgery.
• Cosmetic Surgery: Silicone is a well-known component in creating breast implants and it has many other plastic surgery uses as well as standard medical uses from gels to bandages.
• Personal Hygiene: Silicone is used in a variety of personal hygiene products such as shampoo, shaving gels, hair conditioners and gels. [4]

The present study uses a commercial heat cured silicone rubber formula (including a process aid) and mixing techniques to investigate the effect of varying fumed silica properties—including load, surface area, silica structure level, and surface pretreatment levels—on the rubber processing, curing, and cured physical properties. Based on the results, a simple silica network reinforcement model was developed to explain the changes in processing, curing, and vulcanizate properties of the silicone elastomers. The network is held together by silica-silica interactions and silica-polymer-silica bridge bonds between the silica aggregates. Increasing the silica loading, surface area, and structure level increases the number of interactions and hence the network strength. The pretreatment of the silica surface with organosilane molecules reduces the strength of silica-silica and silica-polymer interactions, therefore, weakening the silica network. Furthermore, the good interrelations between the initial plasticity, crepe hardening, curing, modulus yield, and durometer values strongly supports the concept of the presence of a silica network within the compounds under the low strain conditions of the tests.

In a five-year follow-up of 42 patients with unsatisfactory cosmetic results after enulceation, room-temperature vulcanizing (RTV) silicone was used in the surgical correction of enophthalmos and superior sulcus depression. RTV silicone with a catalyst was placed in a dissected pocket subperiosteally along the floor and lateral wall of the orbit to correct the volume deficit. When vulcanizing in situ into soft silicone rubber, the implant conformed to the orbital wall and did not migrate. We determined tissue tolerance to in situ vulcanizing silicone histologically in 30 rats by inserting prevulcanized and in situ vulcanized material in paired subcutaneous pockets. No statistical difference was noted between the two methods. In 11 cases, the same material was used as a convenient stent to maintain the pressure over a graft and to maintain socket size after the reconstruction of a contrated socket, by filling the socket with RTV silicone which surrounded a Kirschner wire drilled through the lateral orbital rim. [6]


From automobile lubricant, personal hygiene products to electornic casings and cosmetic surgery materials, silicone has become an imortant part of our every day life. Its use is wide and it is contiounsly being used more and more in various aspects of our lives because of its qualities.
