Alpha Technologies has published a study about rubber process analyzers (RPA), viscoelastic properties, and mix quality in a recent Technical Notebook for Rubber News. Authors John Dick and Richard Hanzlik compare the relative advantages of various viscoelastic properties that an RPA can measure. This article is the first in a two-part series by the authors.
Alpha Technologies has published a study about measuring the quality of mixes that contain recycled rubber powders (RRP). The authors compared ASTM test standards that are designed for use with rubber process analyzers and determined which tests are most and least effective with RRPs.
