• Chlorinated Alkanes Market | Global Industry Report, 2027

    Commercial chlorinated alkanes contain 30% to 70% chlorine, are largely inert, practically insoluble in water and hardly evaporate. Most commercial products are liquid with a range of viscosities, depending on the degree of chlorination. There are also solid types that have longer carbon chain lengths, containing 70% to 72% chlorine.

    Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes.The chlorination degree of CPs can vary between 30 and 70 wt%.CPs are subdivided according to their carbon chain length into short-chain CPs (SCCPs, C 10–13), medium-chain CPs (MCCPs, C 14–17) and long-chain CPs (LCCPs, C >17).Depending on chain length and ...

    Composition, structure, and properties. The silicones differ from most industrial polymers in that the chains of linked atoms that make up the backbones of their molecules do not contain carbon, the characteristic element of organic compounds.This lack of carbon in the polymer backbones makes polysiloxanes into unusual “inorganic” polymers—though in most members of the class two organic ...
