“…Generally, for the three composites, σ f increased with increasing carbon black content, showing maxima around 40 phr GPF black, followed by a decrease with further increases of the content of GPF black. This behavior suggested the formation of a compact structure, and above a content of 40 phr GPF, this compact structure became more loose 12. The values of σ f for the M system were higher than those of both the S and T systems.…”

The effect of the vulcanizing system on the mechanical properties of butyl rubber/ethylene propylene diene monomer-general purpose furnace black-(GPF) blends was studied with static and dynamic mechanical measurements for these blends. The classical theory of elasticity was applied to show the mechanical behavior of the rubber-polymer blend and to calculate the degree of crosslinking. From the dynamic mechanical measurements, the elastic modulus, internal friction, and thermal diffusivity were calculated. The observed variations were explained in view of the role played by both the vulcanizing system and the reinforcing carbon black.

“…Moreover, the effect of reinforcing HAF on the network structure, technical properties, and failure of ethylene propylene diene monomer (EPDM) rubber vulcanizates was studied 2. Extensive research3, 4 was carried out on the effect of type and concentration of HAF on the elastic modulus of butyl rubber. The time of vulcanization and its effect on the elastic modulus and the tensile strength of isobutylene isoprene rubber were also investigated.…”

The dependence of equilibrium force (F*) on the strain ratio (α) of carbon black loaded butyl rubber was studied. The relation between elastic constant and volume fraction of carbon black was found in good agreement with that obtained by Guth and Gold relation at low concentrations using the shape factor (f = 6.5). The relaxation time and viscosity (η) were calculated by using stress relaxation of these samples at different compression strains. The same agreement was observed in the relation between viscosity and volume fraction of carbon black concentration. The results are discussed according to the dispersion mechanism of carbon black in rubber. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 1067–1076, 2000

This review of the fundamental aspects of polymer stabilization technology covers aspects of oxidative degradation of polymers, and the deleterious effects of oxygen and the environment: temperature, sunlight, ozone, atmospheric pollutants, water, mechanical stress, adventitious metal, and metal ion contaminants. The role of antioxidants in polymer stabilization with examples to illustrate the basic mechanisms of action and the range of chemical and physical factors that affect performance are discussed. Different classes of antioxidants that act by different and complementary mechanisms are covered. Also included are examples of recent developments and progress in areas of application where melt, heat, and light stabilizers are generally employed, as well as in more targeted areas that benefit specifically from the use of time‐control stabilizers, high molar mass antioxidants, reactive (polymerizable or graftable) antioxidants, and biological antioxidants.
