Costs associated with cleaning method development and validation are minimal relative to those required for other processes where unvulcanized silicone-drug mixtures contact numerous surfaces of both mixing and fabrication equipment.
In order to see the effect of vulcanization on the morphology, SEM image of unvulcanized EPDM/POSS blend with 5 phr POSS was examined, which is shown in Fig.
Among the topics are the basic concepts and behavior of rubber elasticity, characterizing structure in the science and technology of elastomers, the viscoelastic behavior of rubber and dynamics of blends, the rheological behavior and processing of unvulcanized rubber, vulcanization, reinforcing elastomers by particulate fillers, the science of rubber compounding, the strength of elastomers, the chemical modification of polymers, tire engineering, and recycling rubbers.
