The article analyzes the characteristics of a new impression material, Pol-E-Lastic. The material was mixed in which the base and catalyst were proportioned by weight for greater accuracy. The weight ratios, 1.2:10, 1.0:10, and 0.8:10. were equivalent to 20% extra length catalyst, equal lengths catalyst and base and 20% less length of catalyst. The compression specimens were formed by placing the mixed material into a cylindrical two-part split mold measuring 10mm in diameter and 20mm high. The inner surface of the mold was lined with polytetrafluoroethylene (PTFE) tape.
