Abstract
A foam rheometer has been developed based on the impulse theory of lin ear viscoelasticity. The rheometer is a large-volume parallel-plate de vice which operates under gap-loaded conditions, and is designed as an add-on fixture for the Materials Testing System Model 312. The rheome ter provides characterization data of the pre-gel (via the zero-shear viscosity) or the post-gel (via the equilibrium modulus) properties of a foaming cellular polymer with a precision of better than +/- 15%
