... closely replicated actual service conditions. Cylindrical specimens and actual bumpers were fabricated from epichlorohydrin and nitrile elastomers, two materials commonly used in the bumper application. The dynamic behavior of thin circular disks is also studied and brief comparison with the Split...

...KL Fishman; D Machmer The objective of this study was to examine prospective tests for determining the bulk modulus of elastomers used in the construction of elastomeric bearings. Because elastomeric materials are nearly incompressible, relatively slight volume changes are experienced during...

... agreement is seen between values corrected by this method and those corrected by the Bagley method. Since this method uses data from a single die, it should be of interest to industrial technologists concerned with the time and effort involved in correcting data via the Bagley method, KEYWORDS: elastomers...

... in stress relaxation time. Compound viscosity values of polymers having high molecular weight fraction decrease less upon increasing temperatures than polymers having no high molecular weight fraction. The processibility tester can be used to characterize the rheological properties of an elastomer or its...

...M Hudlicky After a short survey of the development of fluorinated elastomers, curing of fluorinated copolymers is described. The discussion includes the main cross-linking agents such as diamines, Schiff bases, dithiols, bisphenols, peroxides, and irradiation, and the modes of action of the agents...

... of stress relaxation and permanent set. Some data on oxidative aging of natural rubber are recalled as a paradigm of chemically degrading elastomers and some simple scaling laws are described which (when they can be established) are useful for predicting longtime behavior from short-time tests. aging...
