Chlorinated paraffins are products obtained by chlorination of linear aliphatic hydrocarbons; various types of liquid chlorinated paraffins can be obtained, differing from each other in the percentage of chlorine and the length of the paraffinic raw material chain (Cloparin Serie). The chlorinated chlorosulfonated paraffins instead come from a process of “chlorosulfonation” that uses both chlorine and sulfur dioxide (Cloparten Serie).

Among the various applications of the different types of Cloparin, its main use is as a PVC plasticizer in total or partial replacement of other traditional plasticizers and in particular for: plastisol, electric cables, floorings, carpets, calendered surfaces, rolled sections, pipe extrusion, low temperature compounds and AE-plasticized PVC. Cloparin is also successfully used in flame-resistant PVC compounds. PVC may itself be considered non-flammable, but when it is plasticized with plasticizers such as phthalates it is deprived of its property. Because of their full compatibility, low volatility, good stability and non-flammability, the various types of Cloparin are used as plasticizers in preparation of solvent and emulsion paints and varnishes.

Besides Cloparin could be used as additive in treatment of textiles: in particular, chlorinated paraffins, due to their polar nature, have much greater bonding to the amino groups of the hide than the animal and vegetable oils normally used as greasing agents. As a softening agent of the leather are better used chlorosulfonated chloroparaffins (Cloparten) which, after saponification and thanks to the double functional group of sulfonic acid salt (polar) that binds to the polars groups of the leather and the chlorinated chain (apolar) that remains outside, give a particular softness of the leather. Finally Cloparin and Cloparol are used as additive in formulating lubricating, cutting and other industrial oils.
