Plasticizer
Sebacate - based plasticizers provide excellent compatibility with a range of plastic materials and synthetic rubbers (specifically nitrile rubber and neoprene), superior properties at low temperatures, and good oil resistivity. Some examples are: Dibutyl sebacate (DBS) Di- (2-ethylhexyl)sebacate, Di-octyl Sebacate [15] (or DOS plasticizer)
Natural-based plasticizers and biopolymer films: A review
The great variety of plastic products and its numerous applications have led to the development of new and improved plasticizers in order to meet product quality and specification requirements. Over the last half century, legislation and health safety issues have led to the development of a wide range of currently-available commercial plasticizers.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
What Plasticizers Do & How They Affect Properties | Osborne
Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC. By volume, after Polyethylene (PE) and Polypropylene (PP), PVC is the third largest polymer used in products. PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage.

Sub Classification of plasticizers – 1. General purpose plasticizer [GP] - They provide desired flexibility to PVC, balancing overall quality with low cost. Examples are DIHP, DOP (DEHP),...
- What materials use plasticizers?
- Many different materials use plasticizers, including PVC, rubber, plastics, etc. In fact, the discovery of plasticizers has almost made the polymer industry possible. Without plasticizers, most polymers would be too brittle and hard to use.
- What are the advantages of plasticizers?
- · Scalability · Processability Plasticizers can improve the flowability and thermoplasticity of polymers by reducing the viscosity, glass transition temperature (Tg), melting temperature (Tm), and elastic modulus of the finished product, without altering the basic chemical properties of 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 are plasticizers used for?
- Plasticizers are also often added to concrete formulations to make them more workable and fluid for pouring, thus allowing the water contents to be reduced. Similarly, they are often added to clays, stucco, solid rocket fuel, and other pastes prior to molding and forming. For these applications, plasticizers largely overlap with dispersants.
- How are plasticizers classified?
- 3. Classification of plasticizers Plasticizers are usually classified based on their chemical composition. Different plasticizers can affect the physical and chemical properties of materials. Therefore, a specific plasticizer is needed to change performance in a specific direction to meet the requirements.
- What are plasticizers & superplasticizers?
- In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improved workability and strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
