The following are characteristics of an ideal alginate impression material: cost effective easy to mix adequate flow properties non-toxic or irritating sufficient strength to avoid tearing material upon removal from the mouth acceptable working and setting times Some functional properties. The gelation time is primarily controlled by the concentration of Na4P2O7 in solution acting as a retarder, while the level and particle size of the alginate and CaSO4 X 2H2O also affect the kinetics through the dissolution rates and concentration effects. Although this process of bond interchange and that of continued polymerization during deformation may be contributory mechanisms to permanent set, bond rupture appears to be the primary mechanism.
