Rubber Compounding - an overview | ScienceDirect Topics

The first step in rubber compounding is mastication or polymer "breakdown". This is essentially development of the polymer's viscoelasticity to make it receptive to the additives. Most synthetic elastomers are produced with the uniformity in chemistry, viscosity and stability that minimizes or precludes the need for mastication.
