Stiffness—hysteresis charts show differences in dynamic mechanical properties resulting from compounding changes, such as elastomer, crosslink density (and, under certain test conditions, crosslink type), filler type(s) and loading (s), and softene

The principal properties of carbon black which must be considered in the study of rubber mixtures containing carbon black are (1) particle size and the related property, (2) surface area, (3) hydrogen content, (4) oxygen content, and finally a proper

A simple technique of sample preparation using dry carbon black samples has been developed which gives a carbon black surface of reasonably reproducible reflectance, using a commercially available and reasonably priced reflectance meter. The reflecta

A simple method of pretreating carbon black has been developed which permits measurements to be made on the dry carbon black which reflect on the basic property called “structure.” Correlation between these measurements and extrusion shrinkage of

A system of analysis has been described which permits determining the type of rubber grade carbon black in a vulcanizate. The carbon black is removed from the vulcanizate by vacuum pyrolysis at 850° C and its reflectance after acid washing and compr

1. The various tint tests correlate with each other—it does not make much difference which of the three procedures is used. The discrimination between similar blacks is comparable. Specific surface areas obtained by the three methods are comparable

Results of this infrared study give strong qualitative support for the presence of quinones and support the presence of lactones. Considerable chemical reactivity is associated with the presence of these two groups. Absorption typical of phenols and

Selected physical tests were made on natural rubber vulcanizates prepared with six levels of each of six different curing systems. These combinations produced different types of crosslinks which were subjected to analysis using a combination of swell

Since 1955 we have used lithium aluminum hydride for qualitative and quantitative analysis of the polysulfide content of various types of rubber vulcanizates. The first results were of qualitative or semiquantitative value, but by 1959 we felt that t
