Is there an exact formula for Silly Putty?

Post by cas512 »

I am doing a chemistry project on Silly Putty. I know that sounds boring, but it is a very interesting object. Anyway, I was wondering if there was a chemical formula for Silly Putty. I am not looking for how to make it, but a formula. (example: water= H20) Thank you for your time.

Hi!
I don't think there is an exact formula for Silly Putty but you should be able to find some of the formulas of its components. For example, one of the materials which makes up Silly Putty, PDMS, has this formula: (H3C)3SiO[Si(CH3)2O]nSi(CH3)3

Hope this helps!

Silly putty is a very interesting compound and its pretty complex. Wikipedia at http://en.wikipedia.org/wiki/Silly_Putty in the Description section says that Silly Putty is composed of 65% bleep siloxane (hydroxy-terminated polymers with boric acid), 17% silica (crystalline quartz), 9% Thixatrol ST (castor oil derivative), 4% bleep, 1% bleep cyclopentasiloxane, 1% glycerine, and 1% titanium dioxide[citation needed].
