Tensile Creep Studies on Filled Polychloroprene Elastomer
Lacroix F., Tougui A., Berton G., Ranganathan N., Neelakantan N.

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.
