The second edition of this reference is a compilation of multipoint performance data of plastics exposed to varying conditions of temperature and humidity. Additional plastics families have been added, obsolete products have been removed and replaced, approximately two thirds of the graphs are new, and all tables have been completely revised to contain extensive additional data. More than 70 types of plastic are covered, and the chemistry of each type is summarized. Sections covering polymer chemistry, property measurement, ASTM and ISO testing procedures, and polymer selection provide a basis for understanding the data and how to use it. More than 1000 graphs and tables allow for easy comparisons of a wide variety of plastics products.
