Chlorinated Ester Plasticizers - ResearchGate
Stabilized chlorinated esters (CEs), specifically those derived from esters of palm kernel, palm, and coconut oils, act as viable replacements for chlorinated paraffins (CPs) as secondary...
A targeted review of bio-derived plasticizers with flame
Similar to the above-mentioned examples with soybean oil, another group pursued the use of unsaturated fatty acid methyl ester (FME), which was chlorinated (chlorine reacting with the unsaturated double bonds—Fig. 3) and was used as a co-plasticizer for PVC coating. While adding additional chlorine content to the plasticizer is a way to
A simple approach with scale-up potential towards
Chlorinated fatty acid methyl ester (CFAME) was synthesized by addition reaction between unsaturated FAME and chlorine gas. Briefly, dehydrated FAME (80 g) were introduced into a 250 mL three-necked flask, which was equipped with a thermometer, a magnetic stirrer and an absorbent for exhaust gas.
A Strategy for Nonmigrating Plasticized PVC Modified with
The characteristic temperatures of the T d, T p1 and T p2 for neat PVC decreased gradually from 278.4, 291.5 and 467.4 °C to 210.7, 234.3 and 463.7 °C with increasing substitution of chlorine
Plasticizers: Types, Uses, Classification, Selection & Regulation
They are mostly low cost oils having limited compatibility in PVC. They are added to reduce cost and in some cases to improve fire resistance. Examples of extenders include naphthenic hydrocarbons, aliphatic hydrocarbons, chlorinated paraffins (fire resistance) and others. Processing with Plasticizers
- Can methyl ester be used as a co-plasticizer in PVC coatings?
- When combined with di-(2-ethylhexyl) phthalate (DOP) in PVC formulations, the chlorinated fatty acid methyl ester is qualified as a co-plasticizer while conferring flame retardancy upon the PVC coatings.
- What is chlorine fatty acid methyl ester (cfame)?
- Chlorinated fatty acid methyl ester (CFAME) was synthe- sized by addition reaction between unsaturated FAME and chlorine gas. Briefly, dehydrated FAME (80 g) were in- troduced into a 250 mL three-necked flask, which was equipped with a thermometer, a magnetic stirrer and an absorbent for exhaust gas.
- Who supplies fatty acid methyl ester and epoxidized fatty acids?
- Unsaturated fatty acid methyl ester (FAME, iodine value = 62 gI2/100 g) and epoxidized fatty acid methyl es- ters (EFAME, epoxy value = ca. 5.8%) were supplied by Jingu Plasticizer Co., Ltd. (Shijiazhuang, China). Chlor- ine gas (Cl2, 99.8%) was purchased from Keyuan Gas Co., Ltd. (Chengdu, China).
- Are engineered plasticizers compatible with PVC coatings?
- covalently attached to the plasticizer, the engineered prod- ucts should be totally compatible with PVC, which would not compromise the mechanical properties of the PVC coating. This conclusion was verified herein by measuring the tensile strength and elongation at break of the PVC coatings.
- Can CPS be used as secondary plasticizers in PVC?
- In addition, due to environmental concerns surrounding chlorinated paraffins, the case to use CEs as a viable replacement for CPs as secondary plasticizers in PVC is only strengthened due to their relatively low toxicity and good biodegradability.

- Are polyvinyl chloride plasticizers flammable?
- As an imitation of genuine leather, polyvinyl chloride (PVC) artificial materials are versatile, but suffers from being flammable due to the presence of large amounts of combustible plasticizers. Under such circumstance, intrinsically flame-retardant plasticizers displaying dual functions have been a subject of intensive research interest.
