Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Analytical methods for the determination of DEHP plasticizer
These methods are suitable for the detection and quantification of plasticizer amounts over a broad range of values, depending on the media and the plasticizer [73]. In the work by Luo et al., an ethanol/water mixture was used as an extraction screening vehicle in order to evaluate DEHP released from medical devices that come into contact with
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...

The type and concentration of plasticizer(s) in the shell is related to the composition of the ll, i.e. the possible interactions with the ll, the capsule size and shape, the end use of the product and the anticipated storage conditions. The ratio by weight of dry plasticizer to dry gelatin (P/G) determines the strength of the shell and
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- Why is the introduction of a plasticizer important?
- The introduction of a plasticizer into a polymer composition is important from a practical and theoretical point of view. Lowering the glass-transition temperature of the polymer with the introduction of a plasticizer makes it possible to expand the temperature range of its highly elastic state, that is, to increase its frost resistance.
- Are plasticizers environmentally friendly?
- Four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed by gas chromatography (GC) and infrared spectroscopy (FT–IR) analyses, and their physicochemical properties and thermal stability (TGA analysis) were investigated.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- Which plasticizers have the best compatibility and plasticizing effects?
- Furthermore, plasticizer migration studies showed that the synthesized plasticizers had the best compatibility and plasticizing effects. Compared to DINP and DEHP, the migration was as much as 70% lower for each plasticizer concentration.
- How does a new plasticizer work?
- Thus, studies have shown that the new plasticizer is characterized by high technological indicators—the thermal stability and efficiency of the plasticizing action—and also contributes to an increase in the fluidity of the melt of polymer compositions and the expansion of the temperature range for processing compounds based on it.
