Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Selecting Plasticizers for Adhesives and Sealants
By far, the largest application of plasticizers is as a flexibilizing additive in plastic products such as food packaging, wire and cable insulation and medical devices. In these markets plasticizers are mainly used with polyvinyl chloride (PVC), but many other rigid polymers are plasticized for practical use.

Eastman TOTM plasticizer (Tris (2-Ethylhexyl) Trimellitate) is the ideal PVC plasticizer for use in applications where low volatility is of supreme importance, such as wire and cable insulation and interior automotive. It also has properties that are required for dishwasher gaskets and photograph storage.
Influence of Polyol Plasticizers on the Properties
Polyol possesses similar groups with PVA, which could form hydrogen bonding with –OH of PVA, decrease the original inter- and intra-molecular hydrogen bonding between PVA and destroy the structural regularity effectively. Therefore, polyol is the most common used plasticizers for PVA.
Plasticizers in Paint & Coatings: Uses, Types and Selection Process
The class of chemicals called "phthalates" are the most commonly used plasticizers. & odorless liquids, manufactured in large quantities. In Europe, more than 90% of the total volume phthalates are produced & used to plasticize PVC (polyvinyl chloride) to make flexible PVC products.
- Which plasticizer is used to plasticize PVA resin with a DP of 2400?
- In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400. Both PVA/plasticizer films possess excellent optical transmittance and mechanical ductility, whereas the films blended with DEA exhibit higher strength than the PVA/GLY films.
- Can glycerol and diethanolamine be used to plasticize PVA resin?
- Optimization the plasticizing conditions is one means of addressing this issue. In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400.
- Why is plasticized PVA better than Gly?
- The plasticized PVA system had better mechanical properties, manifested as higher strength and greater toughness of the PVA/DEA films compared to those of the GLY-containing congeners under the same conditions, while maintaining the transmittance.
- 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.
- 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.
- What is the standard deviation for PVA with 10 wt% DEA plasticizers?
- For PVA with 10 wt% DEA plasticizers, the standard deviation of the coordinates was 6.33 × 10 −4, while that of GLY was 6.38 × 10 −4. When the concentration of DEA exceeded 10wt%, the standard deviation of coordinates remain nearly unchanged with increasing DEA content.
