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.

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.
- What are external plasticizers?
- External Plasticizers. There are two groups of external plasticizers, pri-mary and secondary. A primary plasticizer, when added to a polymer, causes elon-gation and softness to be increased. These changes are brought about by mech-anisms described in the following section.
- What is the difference between external and internal plasticizers?
- The external plasticizing route is more common because of lower overall costs, and the use of external plasticizers allows the processor a certain degree of freedom in developing formulations for a range of products. Internal Plasticizers. There has been much dedicated work on the possi-bility of internally plasticized PVC (FPVC).
- What theories explain external plasticizer action?
- Four general theories have been proposed to explain external plasticizer action. Some theories involve detailed analysis of polarity, solubility, and interaction pa-rameters and the thermodynamics of polymer behavior, whereas others treat plas-ticization as a simple lubrication of chains of polymer from each other.
- What is a plasticizer used for?
- Plasticizers are used with acrylics to produce tough flexible coatings. Com-patabilities with common plasticizers are up to 10 wt% although with low molec-ular weight plasticizers, it can be higher. Plasticizers for acrylics include most of the common esters.
- What is a plasticizer in chemistry?
- "Plasticizers". In: Encyclopedia of Polymer Science and Technology Table 1. Commonly Used Plasticizers aTo convert Pa to mm Hg, divided by 133.3. bl is linear. modifying the polymer or monomer so that the flexibility of the polymer is in-creased.
- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost-performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processibility, permanence and other performance properties.
