Classification of plasticizers - Oxoplast
Classification of plasticizers. Plasticizers (softeners) are softening substances which reduce the intensity of intermolecular interaction and increase the mobility of polymer chains. As a result lower glass transition temperature, hardness, strength and increased flexibility of polymer is achieved . Plasticizers also act as an internal lubricant.
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.

Types And Differences Of Commonly Used PVC Plasticizers
Types And Differences Of Commonly Used PVC Plasticizers [Nov 25, 2017] 1、Fatty acid esters Low temperature performance of fatty acid esters is very good, but poor compatibility with PVC so it can only be used as cold plasticizer with phthalates. The most commonly used varieties are dioctyl adipate and dioctyl sebacate. The company is located in:
Plasticizer
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 the different types of plasticizers used for PVC?
- The most common are: diisononyl phthalate (DINP), di-2-ethylhexyl phthalate (DEHP, sometimes also referred to as DOP) and diisodecyl phthalate (DIDP) which have the well balanced properties described above. These plasticizers account for about 80% of all plasticisers used for PVC.
- 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.
- How many types of plasticisers are there?
- There are more than 300 different types of plasticisers of which about 50-100 are in commercial use. The most commonly used are phthalates and adipates. PVC is basically rigid at normal temperature. This is due to the short distances between the molecules since there are strong pulling forces between them (intermolecular forces).
- 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 the most common plasticizers?
- At present, the consumption of phthalates accounts for 80-85% of the total plasticizer consumption, of which the most commonly used are dioctyl phthalate and diisooctyl phthalate. (1) Dioctyl phthalate (DOP) colorless oily liquid with special odor.
- Which PVC products are softened by plasticisers?
- PVC products which are softened by plasticisers are called soft (flexible) PVC products. In Europe, about 30 % of the total PVC resin production is used for flexible PVC products. Importantly, plasticisers are not just additives (like pigments or fillers).
