CREEP BEHAVIOR OF CROSSLINKED POLYETHYLENE,
Abstract
In a vulcanized polyethylene, creep is a sensitive measure of the thermal stability of the compound. Creep is dependent upon time, temperature, applied load, state of cure and formulation. The creep test is very responsive and very versatile since the conditions are readily altered to fit the polymer under study; it is many times faster than conventional aging methods, and correlates well with accelerated oven aging; and it has a wider span of utility in that it monitors a polymer's useful life anywhere between incipient to gross degradation. Creep varies directly with the percent extract and swelling ratio and indirectly with the Hot Modulus. Also, creep provides an accurate approximation of the degree of crosslinking. (Author)
