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.

The plasticizers are added to the plastics via copolymerization. The plastic remains permanently flexible and the plasticizer cannot diffuse out. Further processing of many materials would hardly be possible without the addition of plasticizers. They are therefore used in large quantities in plastics, paints, coatings and rubber articles.
PVC Plasticizers and Stabilizers Following Safer Sustainable
PVC Plasticizers Overview Plasticizers are for, the most part, phthalate-based ester additives that impart elasticity to PVC (PolyVinyl Chloride) to soften it, make it flexible and bendable for application development purposes.

applications are plasticizers, and a major application of them is related to polyvinyl chloride (PVC) as one of the leading polymers in the European polymer market.[3] After the poly-olefins polyethylene (PE) and polypropylene (PP), PVC is accounted for the third-largest share of European production volume of plastics in 2018.[3a] PVC has a
- What is a plasticizer in PVC?
- A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
- 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.
- 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.
- What are plasticizers used for?
- These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare. Plasticizers serve as essential additives in enhancing the performance of PVC. By reducing the glass transition temperature, they enable products to maintain functionality under various conditions.
- What are the different types of PVC plasticizers?
- 1. General purpose plasticizer [GP] - They provide the desired flexibility to PVC, overall balancing quality with a low cost. Examples are DIHP, DOP (DEHP), DINP and DIDP. They can be used along with secondary plasticizers to reduce the cost. DIDP evaporates 76% less than DOP.
- Which PVC material is used in plasticizers?
- Soft or flexible PVC products like extruded soft tubing, profiles and sheeting, thin calendared sheets, etc. make use of suspension-grade PVC. Since plasticizers are dissolved in SPVC (PVC is not dissolved in plasticizers) during the mixing process, the higher the porosity of PVC grain, the higher the rate of plasticizer absorption.
