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 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 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 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 is a plasticizer?
- A plasticizer is a non/low-volatility liquid or solid substance which are generally colorless and odorless. When they are incorporated into raw polymers like a type of plastic or rubber, their flexibility would get improved and it would help us to shape and mold them easier.
- Does a primary plasticizer increase Elon-gation and softness?
- 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. A secondary plasticizer, when added to the polymer alone, does not bring about these changes and may have limited compatibility with the 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.
