Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Plasticizer - an overview | ScienceDirect Topics
One major use of plasticized PVC is automotive underbody coatings; these products are highly filled plastisols that are commonly based upon GP plasticizers often with a fast-fusing plasticizer added to improve processability.

2. How is DEHP used? - GreenFacts
The main use of DEHP is as a plasticizer in polymer products (in EU this is more than 95% of the total use of DEHP), mainly in flexible PVC. The content of DEHP in flexible polymer materials varies but is typically around 30% (w/w). Flexible PVC is used in many different articles e.g. toys, building material such as flooring, cables, profiles
Plasticizer use in Adhesives and Sealants - Chemceed
A plasticizer is an additive used to increase flexibility or workability of a polymer system. Plasticizers typically affect the viscosity, lower the glass transition temperature, and lower the elastic modulus of a product. Phthalates and terephthalates are an example of effective plasticizer chemistries used in caulks and sealants.
- What is a plasticizer & how does it work?
- A plasticizer is an additive that when added to another material makes that material softer or pliable. Although this definition can be applied to a variety of products, the word “plasticizer” generally refers to materials used in plastics.
- Why are plasticizers important?
- Plasticizers are vital to the plastics industry, particularly in improving the properties of materials such as PVC.
- Where are plasticizers used?
- Plasticizers are used in large quantities in plastic additives. Plasticizers are mainly phthalates with good comprehensive performance and low prices. The consumption in the world’s four major production and consumption countries and regions – the United States, Western Europe, Japan, and China accounts for 70% to 90%.
- What polymers use plasticizers?
- Other polymer systems that use small amounts of plasticizers include polyvinyl butyral, acrylic polymers, poly (vinyldiene chloride), nylon, polyolefins, and certain fluoroplastics. Plasticizers can be used with rubber, although more often these materials fall under the definition of extenders, rather than plasticizers.
- What are plasticizers used in PVC & other plastics?
- Plasticizers used in PVC and other plastics are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. These compounds are selected on the basis of many critieria including low toxicity, compatibility with the host material, nonvolatility, and expense.
- 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:
