Internal plasticizer and external plasticizer Plasticizers can be divided into two types, that is, the internal plasticizer and the external plasticizer. The internal plasticizer is actually a part of the polymer. The general internal plasticizer is the second monomer introduced in the polymerization process of the polymer.

The former method is termed "Internal Plasticization" while the latter, "External Plasticization ". Wherever possible, "Internal Plasticization" is the preferred route since adding a plasticizer entails careful selection for compatibility, processibility, permanence and other performance propertie s which in turns are dependable on solubility ...

The most widely used external plasticizers include esters formed from the reaction of acids or acid anhydrides with alcohols. There are two main groups of external plasticizers: A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities.

Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of ...

The HP groups, i.e., internal plasticizers, comprised 12, 24 and 43 wt.% of HPX0.3, HPX0.6, and HPX1.1, respectively, while sorbitol was added as the external plasticizer at 10 and 20 wt.%. Thus, the combined amount of internal and external plasticizers in HPX0.6/20s and HPX1.1 films was similar (44% and 43%, respectively).

Classification of plasticizers - Oxoplast

Plasticizers (softeners) are softening substances which reduce the intensity of intermolecular interaction and increase the mobility of polymer chains. As a result lower glass transition temperature, hardness, strength and increased flexibility of polymer is achieved . Plasticizers also act as an internal lubricant.

Plasticizers are also often used when pozzolanic ash is added to concrete to improve strength. This method of mix proportioning is especially popular when producing high-strength concrete and fiber-reinforced concrete. Adding 1-2% plasticizer per unit weight of cement is usually sufficient.
