Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer widely used in large applications due to the excellent balance between cost and properties. Due to the environmental and human health concerns of consumption of petrochemical-based plasticizers, the use of bio-based plasticizers has been increasing. The new blends of PVC made with green
testing and content plasticizer of - Influence PVC 11
Experiment 11: PVC - Influence of plasticizer content and testing temperature. Aim: (a) To make "plastisol" compositions (suspension of fine spherical particle of PVC in a liquid like di-octyl phthalate, DOP), in which the PVC/DOP ratio is varied. (b) To measure the shear-stress-shear rate relation of these plastisol compositions,
Methods for determination of plasticizer migration
Plasticizer acts like a lubricant that intercalates the rigid PVC chains for an easy movement, otherwise pristine PVC would be too brittle for any practical purpose. The dosage of plasticizers required in PVC formulation varies according to the end application.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.

- How do we detect plasticizer migration from PVC synthetic materials?
- To this end, this review is compiled as a general review of the methods now available for detecting plasticizer migration from PVC synthetic materials via three different mechanisms (i.e., volatilization, exudation, and extraction), with an emphasis on the instrumentation, methodology, advantages, and limitations of each method.
- How to evaluate volatilization propensity of plasticizers from PVC synthetic materials?
- Currently, the most commonly employed methods that enable quantitative evaluation of the volatilization propensity of plasticizers from PVC synthetic materials are fogging test and activated carbon method.
- What is the plasticizer content of PVC?
- The plasticizer content differs depending on the commercial use of the material since the level of plasticizer determines the physical properties of the PVC. The plasticizer used for the material in this study was dioctyl phthalate (DOP). The amount of DOP present in PVC is typically determined by gravimetry after Soxhlet extraction.
- How to evaluate the exudation tendency of plasticizers from PVC coatings?
- Specimen arrangement as described in ISO 177:2016 (E) that evaluates the exudation tendency of plasticizers from PVC coatings into other materials when they are brought into close contact Theoretically, the loss in mass of the specimens should be equal to the increase in the mass of the absorbent backing discs.
- How to compare plasticizer volatilization from PVC?
- Thus, some practitioners refer to follow ISO176:2005 (E) that specifies an economically accessible method, intended for a rather rapid comparison of plasticizer volatilization from PVC in the presence of activated carbon. In this method, the PVC synthetic materials are cut into discs of 50 mm ± 1 mm in diameter and 1 mm ± 0.1 mm in thickness.
- Can FT-NIR determine plasticizer content in polyvinyl chloride (PVC)?
- Broad, overlapping and low intensity peaks usually dominate the NIR spectrum. An experiment was conducted to develop an FT-NIR method for the determination of the plasticizer content in polyvinyl chloride (PVC). PVC is used for many products such as toys, cables and foils.
