Phthalates in Food Packaging and Food Contact Applications
The FDA revoked authorizations for the food contact use of 23 phthalates and two other substances used as plasticizers, adhesives, defoaming agents, lubricants, resins, and slimicides.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.

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.

Plasticizers: Materials, Action and Uses | Admixtures
Out of these materials, sodium, calcium and ammonium ligno sulphates are most popular. The amount of plasticizers used varies from 0.1% to 0.4% by weight of cement. At constant workability, the reduction in mixing water by the use of 0.1 to 0.4% of plasticizer is expected from 5% to 15%, which naturally increases the strength.
- What are plasticizers used for?
- Plasticizers are used to reduce processing temperatures, improve impact resistance, and to increase flexibility and resistance to cracking in these materials. Cellulose acetate can be plasticized with more polar esters such as dimethyl and diethyl phthalate.
- Why is plasticization important?
- Plasticization is the process of making the final plastic product more flexible. By incorporating the right type and amount of plasticizer you can tweak your formulation. Hence, selecting the right plasticizer for a specific application is very critical to make the product softer. Plasticization can occur both internally and externally.
- What is a plasticizer in chemistry?
- The Council of the International Union of Pure and Applied Chemistry (IUPAC) adopted the following definition of a plasticizer: “A plasticizer is a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility.”
- What plasticizers are used in safety glass film?
- The most common plasticizers used in safety glass film are the di-2-ethylhexanoic acid esters of tri- or tetra-ethylene glycol. These esters give excellent compatibility, clarity, and resistance to sunlight. Many cellulosic materials, including cellulose nitrate, are compatible with relatively high levels of plasticizers.
- 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.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
