How to Select the Right Plasticizer for Polymers?
Plasticizers are additives that increase the flexibility, extensibility, and workability of some plastic materials like PVC. These plasticizers are either liquids with low volatility or solids. They decrease the attraction between polymer chains, increasing the flexibility of the plastic material. What are the Requirements for Plasticizers?
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are most widely used additives in plastics. They are generally available as non-volatile, colorless liquids. Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt.

Some plasticizers develop a high potential regarding scope of use, but they are designed for a specific use. Unimoll AGF, our largely bio based plasticizer, was developed for the use in articles intended to come into contact with foodstuffs. Our Uniplex Benzoates are mainly solid special plasticizers used in hot-melt adhesive & equipment

Plasticizers increase the flexibility of the crystalline polymers by decreasing the cohesive force of the attraction between the polymer chains and thereby increasing its segmental and molecular mobility. The flexibility of the polymers also depends on the segmental rotation of the polymer backbone.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers have been used to give polymers a permanent adhesive character (pressure sensitivity), or to regulate their adhesion-cohesion balance to achieve removability. For example, plasticizers can be incorporated into peelable pressure-sensitive adhesive to soften the adhesive, and thus improve peelability and clean removal.
- 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.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. 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.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- What materials use plasticizers?
- Many different materials use plasticizers, including PVC, rubber, plastics, etc. In fact, the discovery of plasticizers has almost made the polymer industry possible. Without plasticizers, most polymers would be too brittle and hard to use.
- What is a reactive plasticizer?
- Learn more. This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials.
- Why are plasticizers used in film coating?
- Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
