How to Select the Right Plasticizer for Polymers?
Plasticizers are the major functional additivestransforming the physical properties of polymers such as PVC, PU, acrylic, nitrile and rubbers to create a whole world of flexible and durable finished articles for high demanding applications. The world plasticizer consumption was around 7.82 million MT in 2017, up nearly 25% over 6 years[2].
Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
Selecting Plasticizers for Adhesives and Sealants
Criteria to Select Plasticizers Plasticizers that are used in adhesive and sealant formulations are generally chosen on the basis of the following criteria: Compatibility with a given polymer or set of component ingredients Compounding characteristics Effect of plasticizer on the rheological properties of the polymer

Plasticizers. Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished
Polymers | Special Issue : Green Plasticizers for Polymers - MDPI
Reactive energetic plasticizers (REPs) coupled with hydroxy-telechelic poly (glycidyl azide- co -tetrahydrofuran) (PGT)-based energetic polyurethane (PU) binders for use in solid propellants and plastic-bonded explosives (PBXs) were investigated. The generation of gem -dinitro REPs along with a terminal alkyne stemmed from a series of [...]
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- What is the polymer additives & plasticizers library?
- The Polymers, Polymer Additives and Plasticizers Library features 1,799 spectra collected by Chemir/Polytech Laboratories and Dr. John Kokosa. Samples were run by transmission using one of the following techniques: molded film, capillary film or KBr disk.
- Are secondary plasticizers compatible with polymers?
- Since the primary plasticizers can quickly gel the polymer and have solubilities close to those for the polymer, they rarely leach out of the plasticized material. The secondary plasticizers group’s compatibility with polymers is generally quite limited.
