Apparent Viscosities of Setting Elastomers.

Abstract

The flow behavior of five elastomeric impression materials was determined by extrusion viscometry. Initial viscosity ranged from 400 to 5,100 poise at a shear rate of 2.2 reciprocal seconds. All of the elastomers showed initial non-Newtonian behavior and increased viscosity with time. The data suggest that clinical impression making procedures should be tailored to produce rates of shear commensurate with those required to optimize the flow properties of modern impression materials.
