As you may have heard, Silicones, or "polysiloxanes", are inorganic polymers consisting of a silicon-oxygen backbone (...-Si-O-Si-O-Si-O-...) with side groups attached to the silicon atoms. Certain organic side groups can be used to link two or more of these -Si-O- backbones together. By varying the -Si-O- chain lengths, side groups, and crosslinking, silicones can be synthesized into a wide variety of materials. They can vary in consistency from liquid to gel to rubber. The most common type is linear polydimethylsiloxane or PDMS. The second largest group of silicone materials are based on silicone resins which are formed by branched and cage-like oligosiloxanes. Silicones are odorless, colorless, water resistant, chemical resistant, oxidation resistant, stable at high temperature, and do not conduct electricity. They have many uses, such as lubricants, adhesives, sealants, gaskets, breast implants, pressure compensating diaphragms for drip irrigation emitters, sex toys, and Silly Putty. An enormous controversy developed during the 1990s around concerns that the silicones in breast implants were responsible for several diseases. Health concerns included pain, deformity and the less obviously related connective tissue disorders (eg. scleroderma, arthritis) and chronic fatigue syndrome. Leakage of silicone from implants could be demonstrated easily but proof of its safety or otherwise was lacking. Silicone implants have been removed from the market in some countries (notably the US) because of the 'Silicone Controversy' but are extensively used elsewhere. Silicone is often mistaken colloquially for elemental silicon, because of the similarity in pronunciation and spelling, but they are entirely different. For example, in the Shakira song "Objection (Tango)", the lyrics "next to her cheap silicon I look minimal" should be "next to her cheap silicone I look minimal."... They are imitations of the human form intended for simulation of sexual acts. They may consist of a representation of a face, the buttocks, genital areas, or the entire body. Most sex dolls are inflatable. with a life-size of a porn star and optionally a hole for lovemaking. More expensive realistic sex dolls exist, the cyberskin; CyberSkin? is the brand-name of a soft material that is intended to emulate the feel of human skin. The technology behind CyberSkin? is a "new Aerospace 601 computerized injection molding machine, originally designed by NASA engineers..." Similar material is available under other brand names, such as Ultraskin, Eroskin, Softskin, Cyber Jel-lee, Futurotic and UR3. We also have Dildo, Cock-rings, Pocket Pussies, Cock-rings..etc., and their accessories. While all synthetic skin materials are very soft, it is important to stress the proper care of any of these products. Cyberskin is very porous and tends to discolour and tear easily. Any adult toy should be cleaned after each use and allowed to air dry before being stored in a breathable bag. As with any soft plastic an anti-bacterial cleaner specially designed for adult toys is highly recommended, and is available...
