What is the chemical structure of Silly Putty?
The original coral-colored Silly Putty is composed of 65% dimethylsiloxane (hydroxy-terminated polymers with boric acid), 17% silica (crystalline quartz), 9% Thixatrol ST (castor oil derivative), 4% polydimethylsiloxane, 1% decamethyl cyclopentasiloxane, 1% glycerine, and 1% titanium dioxide.
What is polydimethylsiloxane made of?
Polydimethylsiloxane (PDMS) is the simplest member of the silicone polymer family. It is formed by hydrolyzing Me2SiCl2, which is produced from high-purity SiO2 and CH2Cl2 by the Muller–Rochow reaction.

How do you make polysiloxane?
Linear polysiloxane can be synthesized by both anionic and cationic polymerizations of cyclic siloxanes such as hexamethylcyclotrisiloxane (n = 3) and octamethyl cyclotetrasiloxane (n = 4). Anionic polymerization is initiated by hydroxide, alkoxides, phenolates, silanolates and siloxoanolates.
Is making Silly Putty a chemical change?
By adding the borax solution to the glue mixture, you start a chemical reaction. The glue molecules and the borax molecules react with each other to create a stretchy, bouncy new substance.
What polymer is Silly Putty made of?
silicone oil
Silly Putty is a polymer made from silicone oil and boric acid. A polymer is a chain of molecules that are all tangled up. Silly Putty has flexible molecules that, when smooched by fingers, slide over each other and cause the material to flow. Therefore, Silly Putty is considered an elastomer.
What is polydimethylsiloxane?
PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and other applications.
What is silicone made of?
While the main chain of common organic synthetic polymers consists of repeating carbon (C) atoms, silicone is an “inorganic synthetic polymer” whose main chain is made of polysiloxane, which is the repetition of silicon(Si) and oxygen(O) atoms(1,2).
How toxic is dimethicone?
Dimethicone Copolyols are chemically and physically inert ingredients used in cosmetics in a concentration range of less than or equal to 0.1-10%. This compound is, at most, slightly toxic to the rat when administered orally or dermally in a single dose.
Is dimethicone a chemical compound?
Important Chemical Components: The chemical formula for dimethicone (also known as polydimethylsiloxane or PDMS) is CH3[Si(CH3)2O]n Si(CH3)3 where n is the number of repeating monomer units [molecular formula = (C2H6OSi)n]. Silicon dioxide (silica) is the base material from which silicones are derived.
What is polysiloxane paint?
Polysiloxane coatings are industrial coatings used in applications where abrasion, chemicals, high UV and high temperatures are experienced. A Polysiloxane is a polymer with a Silicon-Oxygen backbone.
What is poly silica resin?
POLY SILICA RESIN is the main resin used in the production of auto ceramic coating material. POLY SILICA RESIN is used by diluting in xylene solvent. Creates a glass film layer on the cars. Because of this glass layer, POLY SILICA RESIN protects the vehicles against external factors.
