Selecting Heat Stabilizers for PVC
With phosphates and chlorinated paraffins, you will need more epoxy co-stabilizer, and extra phosphite chelator in a mixed metal barium/zinc or calcium/zinc system. Epoxy plasticizers (epoxidized soybean, linseed oils and tallate esters) are often used in PVC compounds as an auxillary co-stabilizer with mixed metal stabilizer systems.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Chlorinated paraffin with chlorination levels of 52% (CP-52) was selected as an alkyl chloride because its chlorine content was similar to PVC. The purified, final DOP-like plasticizer from...
Release Mechanism of Short- and Medium-Chain Chlorinated
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
Chlorinated Paraffin 52 - Charlotte Chemical
Cereclor is the globally recognized brand of Chlorinated Paraffin of our business partner Inovyn. It is a versatile medium chlorine content grade, used in a large number of industries and applications ranging from its use as a secondary plasticizer, to as a flame-retardant additive in PVC. Main uses: Flame retardant in rubber and polymers. Secondary […]

- 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.
- What is a commercial chlorinated paraffin?
- Commercial chlorinated paraffins are complex mixture of poly chlorinated n-alkanes, containing thousands of homologous and isomers, which are not completely separated by standard analytical methods. They belong to the group of UVCB (substances of unknown and variable composition, complex reaction products or of biological materials).
- 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.
- 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).
