Release and Gas-Particle Partitioning Behaviors of Short
Chlorinated paraffin (CP) mixture is a common additive in polyvinyl chloride (PVC) products as a plasticizer and flame retardant. During the PVC plastic life cycle, intentional or incidental thermal processes inevitably cause an abrupt release of short-chain CPs (SCCPs). In this study, the thermal processing of PVC plastics was simulated by heating PVC flooring at 100–200 °C in a chamber
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Abstract. 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
Short- and medium-chain chlorinated paraffins in plastic
The mean concentrations of short-chain chlorinated paraffins (SCCPs) in the PP and PE samples were 60.0 and 54.5 μg/g, respectively. The medium-chain chlorinated paraffin (MCCP) mean concentrations in the PP and PE samples were 62.7 and 9.23 μg/g, respectively. The carbon congener group profiles of SCCPs and MCCPs in the samples were different.
Short- and medium-chain chlorinated paraffins in polyvinyl
Chlorinated paraffins (CPs), including short-chain CPs (SCCPs) and medium-chain CPs (MCCPs), are hazardous chemical additives widely applied as plasticizers and flame retardants in polymers, mainly in polyvinyl chloride (PVC). In 2017, SCCPs were listed under the Stockholm Convention on Persistent O
Characterization of short-, medium- and long-chain
Research on the environmental occurrence of long-chain chlorinated paraffins (LCCPs) in ambient fine particulate matter (PM 2.5) is still scarce.In the present study, short-chain chlorinated paraffins (SCCPs), medium-chain chlorinated paraffins (MCCPs) and LCCPs were simultaneously quantified and profiled in PM 2.5 samples collected from 96 primary or secondary schools in the Pearl River Delta
- What are plasticizers & chlorinated paraffins?
- Plasticizers > Chlorinated Paraffins Chlorinated paraffins are obtained by the chlorination of hydrocarbons. These plasticizers consist of 30-70% chlorine which makes them act like flame retardants too. The higher the chlorine content, weaker is the plasticizing effect of chlorinated paraffins for PVC.
- What is chlorinated paraffin wax?
- Chlorinated paraffin wax is one of the major secondary plasticizers used in flexible PVC manufacturing. Usage of chlorinated paraffin wax increases the flame retardant property in PVC products such as PVC cables and flooring. Additionally, lower cost of chlorinated paraffin wax vis-à-vis other plasticizers lowers the overall cost of manufacturing.
- What is chlorinated paraffin used for?
- Chlorinated paraffin. Acts as a secondary plasticizer for PVC resin compounding and flame retardant. It is chemically inert and non-corrosive, practically non-volatile, non-flammable and imparts... view more Applications PVC>PVC, rigid PVC>PVC, flexible Buildings & constructions>Flooring>Flooring (tiles) Pipes, Hoses & Fittings>Hoses
- 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 much chlorinated paraffin is used in PVC?
- LCCPs account for only a small fraction of the total chlorinated paraffin usage in PVC (estimated at around 0.5 per cent for C18–20 liquid chlorinated paraffins in the late 1990s).
- Are chlorinated paraffins a high molecular weight organochlorine compound?
- Epub 2013 Sep 30. 1 Consultant (retired) to Euro Chlor, Brussels, Belgium. Chlorinated paraffins (CPs) are high molecular weight organochlorine compounds that have been used in a variety of industrial applications for many years.
