Plasticizers or dispersants are additives that increase the plasticity or fluidity of the material to which they are added; these include plastics, cement, concrete, wallboard, and clay. Although the same compounds are often used for both plastics and concretes the desired effects and results are different.

Mainly plasticizer can be used in these three big areas:
1.Plasticizers for concrete increase the workability of the wet mix, or reduce the water required to achieve the desired workability, and are usually not intended to affect the properties of the final product after it hardens.Plasticizers or water reducers( sodium lignosulphonate, calcium lignosulphonate), and superplasticizer or high range water reducers( sodium naphthalene formaldehyde), are chemical admixtures that can be added to concrete mixtures to improve workability. Plasticizers are commonly manufactured from lignosulfonates, a by-product from the paper industry. Superplasticizers have generally been manufactured from sulfonated naphthalene condensate or sulfonated melamine formaldehyde. Adding 1-2% plasticizer per unit weight of cement is usually sufficient. Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical used, use of too much plasticizer may result in a retarding effect.

2.Plasticizers for gypsum wallboard increase fluidity of the mix, allowing lower use of water and thus reducing energy to dry the board. In order to reduce the energy in drying wallboard, less water is added, which makes the gypsum mixture very unworkable and difficult to mix, necessitating the use of plasticizers, water reducers or dispersants. Adding about two pounds of dispersant per thousand square feet (MSF) in 1/2 inch wallboard (15 g/m² of wallboard) is usually sufficient.

3.Plasticizers for plastics soften the final product increasing its flexibility.
