Compounding Processing Guide — Vamac Dipolymers

Compound Formulation Guidelines . The principles of compounding Vamac dipolymers are similar to conventional technology in that curatives, filters, antidegradants, plasticizers and process aids are all used. As with other high-performance, heat-resistant elastomers, the choice of potential additives tends to be smaller and selection more specific.

A REVIEW ON RUBBER COMPOUND MIXING IN BANBURY

Two-roll Mills Every mixer must provide two basic functions, both equally important-acceptable dispersion (intensive or dispersive mixing) and high uniformity (extensive or distributive mixing). The equipment used most often by the rubber technologist is the two-roll lab mill-a device for preparing small quantities of mixed compound.
