rheo·log test instrument, designed to measure the properties of polymers and rubber compounds before, during and after cure. The RPA is said to meet the full range of testing requirements of the complete manufacturing process, including incoming polymer characteristics, incoming raw material tests, masterbatch testing, final compound testing and cured compound testing.

The RPA measures the viscoelastic properties of polymers and elastomeric compounds, providing comprehensive data on key parameters such as processability, cure characteristics and final cured properties, according to the literature.

The high sensitivity of the RPA is said to enable detection of small changes in types and levels of ingredients and subsequent variations in compound properties.
