    The Science of Sex: What's the Difference Between Silicone, Rubber and Silicone Rubber?

    by David Claus, Ph.D.

    Actually, according to chemists, the ’silicone rubber’ in your Clone-A-Willy Kit (or any other silicone sex toy) is not technically considered a silicone, a rubber, OR a silicone rubber.

    'Silicone Rubber' is a common lay-term for various polymeric organosilicon compounds.  These are carbon-hydrogen-oxygen compounds that also contain elemental silicon. In fact, the term silicone itself is actually a misnomer. The suffix ‘one' is used by chemists to denote a substance with a double-bonded atom of oxygen in its backbone. When first discovered, 'silicone' was believed to have oxygen atoms double bonded to each silicon atom, but this is not true!

    'Silicone' can be defined as an inorganic polymer (contains many bonds), and is also technically incorrect, at least according to a chemist.  The technically correct term for the various silicone rubbers you see in sex toys is polysiloxanes or polydimethylsiloxanes.

    'Rubber' is an entirely different molecule altogether. It's actually a carbon-based polymer that’s harvested from trees in the form of latex.  We'd never use latex to cast a penis.  Latex is prone to easy degradation and deformation.  Heat, oil, salts, metals, even air will degrade latex.  Needless to say, your Clone-A-Willy Kit is completely latex and rubber-free!

    Rest assured that Clone-A-Willy uses only platinum cure organosiloxanes, certified completely body-safe and non-reactive. Beware of some sex toys that claim to use 'Body safe silicone' but really use 'tin-cure silicone', which contains toxic elements and is NOT body safe. 

    Your finished Clone-A-Willy dildo is composed of a completely safe, stable molecule that is phthalate free, non porous, and will not degrade, deform, or leach chemicals, ever.
