Plasticizers (UK = plasticisers) 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. The worldwide market for plasticizers in 2004 had a total volume of around 5.5 million tons, which led to a turnover of just over 6 billion pounds.
