Plasticizer - an overview | ScienceDirect Topics
A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed. Unlike other reported methods, this approach increases the interaction between...
Eastman 168 Non-Phthalate Plasticizer | Trusted Leader
Eastman 168 is the preferred non-phthalate plasticizer for PVC, with performance equal to or better than most ortho-phthalate plasticizers. It offers good performance properties, optimal low-temperature flexibility, resistance to extraction by soapy water, and exceptional nonmigration properties.

Versatile High Efficiency Plasticizers Santicizer Plasticizers offer all the benefits of high solvating plasticizers including compatibility in multiple polymer systems including PVC, Polysulfide, Polyurethane and Silane Modified Polymers. Because of their high efficiency, less energy is required to fuse PVC formulations.
Plasticizers: POLYSORB ID, plant-based solutions
BIOSUCCINIUM based plasticizers have been evaluated in various polymers. Succinate plasticizers of average molecular weight are efficient plasticizers and enable excellent low temperature flexibility in PVC compounds.

- Which plasticizer has a low plasticizing efficiency?
- Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
- Why is DOP a good plasticizer for PVC?
- High plasticizing efficiency of DOP for PVC is attributed to DOP’s good compatibility with PVC and its high rate of diffusion in PVC, which result from the interaction between DOP and PVC molecules.
- Why is plasticizer important?
- Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
- How to choose a plasticizer for PVC?
- Using external plasticizers, it is very convenient to select from a variety of plasticizers depending on the desired properties and processability of PVC. Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC.
- Can a plasticizer system be used for soft PVC products?
- However, the system with 1:1 plasticizer over PVC had a Tg below 0 °C, indicating that the system was completely flexible at room temperature and could be used for soft (flexible) PVC products. Figure 5.
- Is cp52 a good plasticizer for PVC?
- However, stronger interactions between plasticizer and PVC will reduce its rate of diffusion in PVC, leading to lower plasticizing efficiency. A compromise is achieved using DOP-O-CP52, yielding PVC with no migration and high plasticization. CP52 appears to be a better choice for DOP.
