Rubber, vulcanized or thermoplastic — Quantitative estimation of Payne effect (filler-filler interaction/filler network) by using dynamic mechanical analyzer or Fourier transform rheology

Scope

This document specifies two dynamic test methods for evaluating nonlinear viscoelastic behavior, filler network integrity, and rubber–filler interactions of vulcanized rubbers and thermoplastics.
Method A: Determination of nonlinear viscoelastic response using Fourier-transform rheology (FTR) under large-amplitude oscillatory shear.
Method B: Determination of filler–filler and rubber-filler interactions using dynamic mechanical analysis (DMA) through strain-sweep testing (Payne effect).
NOTE: Rubber that vulcanizates with more than 80 IRHD hardness will show slippage behaviour at very high strain analysis.
