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.
Plasticizer Definition & Meaning | Dictionary.com
Plasticizer definition, any of a group of substances that are used in plastics or other materials to impart viscosity, flexibility, softness, or other properties to the finished product.
Plasticizer - an overview | ScienceDirect Topics
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.
Plasticizer
Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the demands of the end product's application.
- What is a plasticizer?
- A plasticizer is defined as an additive that is incorporated in a plastic to impart softness and flexibility in order to facilitate the manufacturing process. You might find these chapters and articles relevant to this topic. A plasticizer is a material that when added to another substance, makes that material softer or more flexible.
- 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 plasticization in chemistry?
- The term plasticization refers to the softening and increase in flexibility of a polymer. This change is due to the addition of specific additives, especially plasticizers. A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material.
- What is the role of plasticizers in polymers?
- The primary role of plasticizers is to improve the flexibility and processability of polymers by lowering the second order transition temperature . Plasticizers are actually low molecular weight (MW) resins or liquids, which form secondary bonds to polymer chains and spread them apart.
- 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.
- 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.
