This text investigates the systematic methodologies required to accurately identify various types of plastic materials in a laboratory or industrial setting. Dietrich Braun, a recognized authority in polymer chemistry, provides a structured framework for material analysis. The book utilizes chemical, physical, and thermal testing protocols to differentiate between common polymer resins. The primary argument posits that reliable identification is achievable through a standardized, step-by-step diagnostic approach.

Experts and laboratory technicians frequently cite this work as a foundational reference for polymer identification. Readers often note the technical density of the prose, which is designed for professional application rather than casual reading.
