An Oscillating Blade Microtome for Rubber

Rubber Chemistry and Technology, 1962
Abstract In a study of the equilibrium swelling of rubber in thick oils, thin samples, about 0.1 mm thick, were required so that equilibrium could be reached within a reasonable time. Thin sheets can be molded, but they are frequently very anisotropic and therefore undesirable.
