Rubber aging study physical properties

Anecdotal evidence suggests that rubber outsoles change over time leading to consumer perceptions of decreased performance. The purpose of this ageing study was two fold. First, the physical properties of a standard rubber compound were evaluated over time to quantify changes. Second, simple formula and process adjustments were made to see if it was possible to produce a rubber product that 1) exhibited... 

NMRI has also been used to study the physical ageing of cross-linked natural rubber filled with carbon-black [673]. The non-destructive character of NMRI allows monitoring changes in the material properties without impairing the sample during the analysis, which is of considerable importance especially for uniquely aged samples. The onset of physical ageing in natural rubber can be observed... 

Boettger and Boltet l conducted a multi-year durability study on a series of high-performance artificially- and naturally-aged sealant products. The physical and mechanical properties of seven series of sealants (polyurethane, silicone, polysulfide rubber, polychloroprene, and EDPM rubber) were evaluated after 6000 hours exposure to natural and artificial aging. The artificial aging consisted in exposure to UV radiation at four different temperatures and condensation at 50°C. Samples were also...
