Abstract:

Dynamic mechanical analyzers (DMA) are routinely practiced in the semiconductor industry to measure the viscoelastic behavior of highly filled thermosetting polymers. The highly filled polymers possess unique challenges in viscoelastic property measurements where set-and-forget style of DMA operation do not always produce the most accurate data due to a large change in modulus over operating and/or manufacturing temperature excursions. This paper discusses the unique challenges associated with the highly filled polymers first and proposes a procedure to determine a proper set of testing parameters.
