Polyvinylchloride plastisols

Plasticizers are nsed in polyvinylchloride plastisols and acrylic plastisol compositions. A wide range of plasticizers may be employed, ranging from the inexpensive types such as dioctyl phthalate, diisononyl phthalate, diisodecyl phthalate, dioctyl adipate, and... 

The plasticized product can be produced by mixing the polymer and plasticizers at elevated temperatures, also by dry blending in which the plasticizer is absorbed into the resin and then heated. Solution blending is sometimes used, as well as the plastisol process, in which fine polyvinylchloride powder is dispersed in the plasticizer which is relatively stable until it is heated.
