(b) Aluminum foil, while obviously not a polymer, is included due to its widespread use in package converting and other industries.To top of page

(1) Names which are most widely used to describe the material or family of materials (e.g., polyurethanes and epoxies) at hand are preferred here. Commonly used acronyms and synonyms are also shown.To top of page

(2) CAS (Chemical Abstract Series) numbers are shown where available. In a number of instances, more than one CAS number is assigned to a given polymer — in some cases the details and nuances of these divergences are not at all clear. We have tried to reference the CAS number which appears to have the widest use with reference to the solid state properties of the given polymer.To top of page
