Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic modulus of the finished product without altering the fundamental chemical character of the plasticized material.
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
Plasticizer Definition & Meaning - Merriam-Webster
plasticizer noun plas· ti· ciz· er pla-st-sī-zr : one that plasticizes specifically : a chemical added especially to rubbers and resins to impart flexibility, workability, or stretchability Example Sentences Recent Examples on the Web Celluloid depended on Taiwanese camphor as a solvent and plasticizer.
What is a Plasticizer? - Definition from Corrosionpedia
A plasticizer is either a non-surface active compound or an active substance added to a suspension, usually a mix, to increase the separation of particles and to prevent subsiding or clumping. It helps to improve a material's plasticity or fluidity. Plasticizers may consist of one or more surfactants, but may also be a gas.
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.
- 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 plasticization in film coating?
- Plasticization refers to the modification in thermal and mechanical properties of a given polymer. 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.
- 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 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 plasticizer efficiency?
- Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP. The relationship of hardness and plasticizer concentration expressed in phr (parts per hundred resin) is shown in Figure 3.
- What are plasticizers & superplasticizers?
- In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improved workability and strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
