Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are among the most widely used additives in the plastic industry. They are also usually cheaper than other additives used in polymer processing. Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include:
A QSPR for the plasticization efficiency of polyvinylchloride
On further comparison between the individual descriptors of plasticizer molecule with corresponding descriptors derived from the model, it was found that the physical and structural descriptors correlated well (linear correlation between PE(plasticizer) and PE(model) gave R = 0.9044; mol.vol 1 (plasticizer) and mol.vol 1 (model) gave R
Plasticizer
Phthalate -based plasticizers are used in situations where good resistance to water and oils is required. Some common phthalate plasticizers are: Low Molecular Weight Ortho Phthalates Dimethyl phthalate (DMP), used in fragrances, as an insect repellent, and in several industrial processes as a solvent/carrier
Pevalen - Perstorp
The high performance polyolester plasticizer, Pevalen, is the perfect choice for sensitive applications, such as flooring in hospitals, schools and public buildings, as well as other close-to-consumer applications – e. g. automotive interiors, molded parts, wall coverings and coated fabrics. Pevalen has a unique performance not matched by any other product, have high plasticizing

- Which phthalate is used as a plasticizer for PVC?
- DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- Are polymeric plasticizers adipates?
- These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult. Many have poor low-temperature properties and may be sensitive to moisture. Check out the table below for the benefits of polymeric plasticizers.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- Does a PVC plasticizer need to be labeled in California?
- If it can be demonstrated that a flexible PVC product containing (Proposition 65 listed) DEHP plasticizer, for example, cannot expose a consumer to more than the maximum acceptable daily limit of DEHP (established by the state of California), no labeling is required in California.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
