EFFECTS OF HIGH TEMPERATURE AND HUMIDITY ON OBTURATOR BAND MATERIALS FOR USE WITH 81MM MORTAR CARTRIDGES,

Abstract

Six types of plastic obturator band materials were tested to determine mechanical and dimensional stability under high temperatures and extreme humidity conditions. It was found that high temperature and humidity expanded the outside diameter of the obturators but to such limited extent that obturating characteristics of materials tested should not be significantly affected. Tensile and impact strengths were not significantly affected, though there was an appreciable reduction in percent elongation. (Author)
