Simple Methods for Identification of Plastics 5E

by Dietrich Braun

Overview

Processors and users of plastics often need to determine the chemical nature of a plastics specimen. The highly practical and useful manual, now in a fifth revised and supplemented edition, will enable you to determine the class of plastic of a particular specimen. No extensive knowledge of chemistry is required and yet it is more than a simple tabular compilation. This manual is a handy, highly effective tool for many practical situations. An additional supplement is a chapter that shows strategies for identifying historical plastic objects; this is of particular interest for assemblers, collectors, and conservators.

Editorial Reviews

For plastics, technicians, engineers, and technical customer service representatives who need to identify at least the general class of a mystery plastic but do not have access to the sophisticated and expensive equipment used by the plastics industry. Braun has successfully carried out all of the tests. Annotation c. Book News, Inc., Portland, OR (booknews.com)
