Plasticizers: Types, Uses, Classification, Selection & Regulation
Three types of phthalates (DEHP, DBP, BBP) are banned permanently in any amount greater than 0.1% in children’s toys and certain child care articles. Three additional types of phthalates (DINP, DIDP, DNOP) were banned on an interim basis in any amount greater than 0.1%. CHAP provided its report and recommended the following actions:

Phthalate esters, based on phthalic acid, are the main types of plasticizers used since they satisfy a broad range of processing and performance requirements, as well as a large number of markets. Major phthalates include di(2- ethylhexyl)phthalate (DEHP), also known as dioctyl phthalate (DOP); diisononyl phthalate (DINP); diisodecyl phthalate (DIDP); and di(2-propylheptyl) phthalate (DPHP).
Plasticizer - an overview | ScienceDirect Topics
Plasticizers such as DIDP or DPHP are used for products needing greater permanence; automotive interior trim applications will focus on DIDP, DPHP, L9P, L911P, L11P, and trimellitates to meet fogging requirements.
Databook of Plasticizers - 2nd Edition
Description. Databook of Plasticizers, Second Edition, contains data on the most important plasticizers in use today, including over 375 generic and commercial plasticizers. The data comes from a range of sources beyond plasticizers' manufacturers, allowing for a detailed comparison of properties between different plasticizers.
Plasticizer Selection for Elastomers - Chemceed
DOS, DBP, DOP are compatible with BR, as are some paraffinic, aromatic, or naphthenic mineral oils. Styrene butadiene rubber (SBR) SBR is compatible with most mineral oils, but has limited compatibility with paraffinic oils. Synthetic ester plasticizers are recommended for us in SBR as well.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What are the different types of phthalate plasticizers?
- Among them, the most common are: Phthalate Esters – Produced by esterification of phthalic anhydride or phthalic acid. Obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- 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 a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
