WebThe Polydimethylsiloxane empirical formula is (C2H6OSi)n and its fragmented formula is CH3 [Si (CH3)2O]nSi (CH3)3, n being the number of monomers repetitions. Depending on the size of monomers chain, the non-cross-linked PDMS may be almost liquid (low n) or semi-solid (high n). 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: n Si(CH3)2Cl2 + (n + 1) H2O → HO[−Si(CH3)2O−]nH + 2n HCl The polymerization … See more 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. … See more PDMS is hydrophobic.
