It reviews the present and future international economic connections and their effects on this chemical supply chain to the rubber producers, compounding ingredient manufacturers, custom mixers, rubber fabricators, molders, extruders, and others. This book explains the chemical connectivity of rubber compounding materials and polymers to their chemical feedstocks. It enables the reader to directly link current commercial changes in 178 commonly used chemical feedstocks to hundreds of dif- ferent rubber compounding ingredients, polymers, textiles, and other raw materials. One of the purposes of this book is to explain in simple terms the chemistry involved in the manufacture of these diverse materials. Also, a goal of this book is to explain why these various rubber chemicals and polymers are used, what comparative advantages they provide the rubber industry, and what competing uses they have in other industries. Lastly, this book provides a wide range of technical terms and abbreviations that are currently used in the rubber industry.
