| Summary |
Latex-based technology forms a sizable fraction of natural and synthetic rubber technology and an introduction to the important technologies is beneficial to all practicing technical personnel. This book offers a condensed practical guidance on the technologies used for the production of important latex products. The book begins with a short history of natural rubber latex, formation in the tree and the tapping, storage and conversion of latex to marketable forms. It discusses preservation and concentration of natural rubber latex and the most widely used latex compounding ingredients. Dipping |
