WebNov 10, 2015 · A closer look at the chemicals that make up silly putty can help us explain this strange behaviour. A number of ingredients go into making silly putty: by weight, 65% of it is a compound called polydimethylsiloxane, but colouring agents are also included to give the wide range of colours that the putty comes in. Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones and siloxane. PDMS is the most widely used silicon-based organic polymer, as its versatility and properties lead to many … See more The chemical formula of PDMS is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [Si(CH3)2O] units. Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: See more PDMS is hydrophobic. Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air plasma and argon plasma will work for this application. This treatment renders the PDMS surface hydrophilic, … See more According to Ullmann's Encyclopedia, no "marked harmful effects on organisms in the environment" have been noted for siloxanes.
