Chlorinated Normal Paraffins as Polyvinyl Chloride Plasticizers
The chlorination of high purity molecularsieved normal paraffins yields plasticizers for polyvinyl chloride (PVC) with better properties than chlorinated waxes. The chlorinated n-paraffins are much lighter in color than chlorinated wax and are more thermally stable in PVC formulations.
Release Mechanism of Short- and Medium-Chain Chlorinated Paraffins
Chlorinated paraffins (CPs) as plasticizers are massively added to polyvinyl chloride (PVC) products, during whose life cycle CPs can be continuously released especially under thermal stress. In this study, a PVC cable sheath was adopted as a representative kind of PVC material to investigate the release behaviors of short- and medium-chain CPs (SCCPs and MCCPs) under thermal treatment

FACETS OF CHLORINATED PARAFFIN USED IN PVC FORMULATIONS - LinkedIn
The chlorinated paraffins most frequently used as secondary plasticizers for PVC are those with a medium chain length (C 14 - C 17), with chlorine contents between 45 and 52%. Thermal &...
- Can chlorinated paraffin be used as a secondary plasticizer?
- Although it has limited compatibility with PVC, chlorinated paraffin as a secondary plasticizer may have a stronger interaction with PVC than other secondary plasticizers because it has a chemical structure similar to PVC. In this study, DOP and chlorinated paraffin were chemically combined into a new compound, DOP-O-CP52.
- Can phthalate be used as a secondary plasticizer in PVC?
- In this study, we attached DOP to chlorinated paraffin (CP), acting as a secondary plasticizer in PVC, to prepare a new compound giving PVC highly plasticization without migration. Unlike other reported methods, our approach covalently attaches phthalate to chlorinated paraffin, a low molecular weight compound with a structure similar to PVC.

- Why is chlorinated paraffin better than CP?
- Chlorinated paraffins are lighter in colour than chlorinated wax and are more thermally stable in PVC compound. CP provides good low temperature flexibility. Higher chlorine grades reduce low temp flexibility. CP provides stain resistance in flooring, wall coverings and upholstery. CP provides resistance to aqueous detergent extraction.
- How is chlorinated paraffin made?
- Chlorinated paraffins are manufactured by chlorination of n-paraffin (un-branched) or paraffin wax, normally in a batch process. UV light aids the reaction. The reaction is exothermic and controlled between 80-100 deg C, as follows: CxH (2x+2) + y Cl2 → CxH (2x−y+2)Cly + y HCl (By-product).
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
