Plasticizers for PVC | POLYNT
The plasticizers are organic substances with various characteristics, whose main function is to intercalate the rigid polymer structures of material such as PVC for an easy movement and flexibility, making them more precisely "plastics." The presence of plasticizers in the PVC structure will influence different specific physical-mechanical

Selecting Plasticizers for Adhesives and Sealants
By far, the largest application of plasticizers is as a flexibilizing additive in plastic products such as food packaging, wire and cable insulation and medical devices. In these markets plasticizers are mainly used with polyvinyl chloride (PVC), but many other rigid polymers are plasticized for practical use.

1. General purpose plasticizer [GP] - They provide desired flexibility to PVC, balancing overall quality with low cost. Examples are DIHP, DOP (DEHP), DINP and DIDP. They can be used along with
PVC - Hanser Publications
plasticizer consumption was about one million metric tonnes (2.2 billion pounds), with ExxonMobil Chemical, BASF, Sunoco, and Eastman Chemical Company as the major producers. The plasticizer market in Europe is about 1.3 million metric tonnes (2.8 billion pounds), with the three largest producers being ExxonMobil Chemical, Oxeno, and BASF.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- Are plasticizers compatible with PVC?
- The molecular structure of plasticizers largely determines their effectiveness and compatibility with PVC. Plasticizers typically consist of large molecules that are capable of inserting themselves between PVC chains. This insertion effectively reduces intermolecular forces, allowing the PVC to become more flexible.
- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
- Are phthalate plasticizers good for PVC?
- Phthalate plasticizers have been the conventional choice in the PVC industry for many years. They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices.
- Are PVC resins compatible with plasticizers?
- Compatibility between plasticizers and PVC resins is another fundamental aspect that determines the overall performance of the final product. A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties.
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
