The resistivity of octyl phthalate plasticizers - Price
Abstract The resistivities of commercial octyl phthalatel plasticizers have been measured after treatments of heating, drying, purification by chromatography and addition of salts. The resistivity of pure plasticizer is high but is lowered by water, acid and alcohol. The theory to explain the observations is advanced. Volume 6, Issue 1 January 1966
Recent Attempts in the Design of Efficient PVC Plasticizers
This paper reviews the current trends in replacing commonly used plasticizers in poly(vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency.
The Effect of Concentration and Type of Plasticizer on the
environmental impacts in contact with it. The permanence of plasticizer in polymer is dependent on the size of the plasticizer molecule, thus the larger molecules, the greater permanence of the plasticizer. The higher diffusion rate of plasticizer in the polymer, the lower permanence due to the migration out of the polymer matrix [8, 9

This is because as scientists started to study the health aspects of the plasticizer called “DOP” in the 1970s, they would often incorrectly assume that as DOP was the name applied to the chemical di-octyl phthalate, then the DOP acronym must therefore refer to di-n-octyl phthalate, instead of di-2-ethylhexyl phthalate. So the acronym DEHP
- What is the use of phthalate esters in polymer formulation?
- Phthalate esters are commonly used as plasticizer in polymer formulation; in particular for poly (vinyl chloride) (PVC) formulation.
- What are phthalate plasticizers?
- From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
- What are the plasticizers used in PVC processing?
- There are many plasticizers used in PVC processing, one of those plasticizers is phthalate esters. Phthalate esters are petroleum-based products which are the most commonly used plasticizers in PVC processing.
- Which Plasti-Cizer has the best match of parameters with PVC?
- Table 3.2 shows that benzyl butyl phthalate has the best match of parameters with PVC and it is known to be the most aggressive plasti-cizer of PVC. In the case of phthalates, the longer the hydrocarbon chain of alcohol involved in the plasticizer, the worse the match of its parameters and the worse a solvating power of plasti-cizer.
- How many esterification reactions lead to conversion of di-alkyl phthalates to phthalic acids?
- Two consecutive esterification reactions lead to the conversion of di-alkyl phthalates to phthalic acids.
- What are the plasticizing effects of synthesized plasticizers in PVC?
- The plasticizing effects of the synthesized plasticizers in PVC as plastisol viscosities, thermal stability, glass transition, tensile properties, hardness, migration stability, exudation loss, and volatility stability were measured and compared to DOP.
