INTRODUCTION. The data and information in this booklet have been collected for use in the Materials Courses in Part I of the Engineering Tripos (as well as in Part II, and the Manufacturing Engineering Tripos). Numerical data are presented in tabulated and graphical form, and a summary of useful formulae is included.

The document lists density values for several common plastics and plastic materials to help identify unknown plastic samples and indicates the importance of accounting for changes in crystallinity, additives, and other factors that can impact plastic density.
1 Material Properties of Plastics. 1.1 Formation and Structure. The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions. Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure 1.1).
