Abstract

Tensile creep data on an elastomeric material, polychloroprene, are presented in this paper. The data were collected at four temperatures, 20, 40, 80, and 110°C and four stress levels, 0.4, 0.6, 0.8, and 1 MPa. Each experiment was conducted over a time period of about twelve hours. Two different mechanisms seem to operate for the creep behavior in these ranges. At the lower temperatures, 20 and 40°C, the data are fitted with a new four-parameter equation; the data at different stress levels are combined into a single curve, which can be called a master plot. At the higher temperatures, 80 and 110°C, for the time period used, a single equation cannot fit the data and two equations are used, a four-parameter equation for the initial time, and the Findley equation for the later time.
