Natural-based plasticizers and biopolymer films: A review
Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) [12], [13]. The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary forces among them.
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.

DTDP plasticizer Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is the preferred plasticizer for automotive cable applications and THHN/NMB electrical wire insulation. Learn more Linear plasticizers
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.
Plasticizer - an overview | ScienceDirect Topics
Specialist plasticisers include phosphates for fire retardancy, polymeric plasticisers (low migration) and some newer ‘non-phthalate’ plasticisers such as citrates, benzoate esters, alkyl sulphonic phenyl esters (Mesamoll), di-isononyl cyclohexane-1,2-dicarboxylate (Hexamoll DINCH) and biobased plasticisers (e.g. Grindsted Soft-n-Safe).
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
- What are plasticizers & modifiers?
- Plasticizers and Modifiers are part of the Polymer Additive Business Unit and comprise of a wide range of high-quality products under the brand names Mesamoll ®, Adimoll ®, Unimoll ®, Ultramoll ®, K-FLEX ®, Vitroflex ®, Modulast ®, Uniplex ®, Triacetin, Acetine, and Baymod®. Mesamoll ® is a phthalate-free universal monomeric plasticizer.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- 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 can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- 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.
