Plasticizers solvating

A considerable range of plasticizers is available but those used most commonly are phthalate esters such as dioctyl or dinonyl phthalate (DOP or DNP). If it should be necessary to reduce the temperature of fusion, or to increase the rate of fusion (as with some expandable plastisols) a fast-solvating plasticizer such as butyl benzyl phthalate may be employed. Besides primary plasticizers such as these, less efficient secondary plasticizers (like chlorinated paraffins) can be included with a view to reducing costs and improving flame retardance.

Furthermore, the increased ability to process at higher temperatures reduced the need for strong-solvating plasticizers in the new composition tiles. Thus, GP plasticizers, such as DOP and DINP, are currently used at 50-100 percent of the plasticizer system. When they are not used as the sole plasticizer, the balance is a stronger-solvating plasticizer, such as BBP, DIHP, or a benzoate ester, which improves processability. 

Table 8.3 lists general performance characteristics of dibenzoates selected to illustrate relative performance. Table 8.4 hsts the formulations used. General purpose phthalates are usuaUy employed as the reference for comparison. However, the best comparison for dibenzoates in the phthalate family is butyl benzyl phthalate (BBP), which is a true high-solvating plasticizer. 

Table 8.9 lists starting or basic plastisol flooring formulations for the wear and foam layers as typically used in European products (note the use of organotin stabilizer in the topcoat wear layer). The main difference between North American and European formulations is that North American products often use only high-solvating plasticizers, whereas European equivalents tend to use a blend of general purpose phthalates and high solvators.
