This chapter presents the Table of Poisson's Ratios focusing on parameters such as manufacturer, trade/common name, filler name, approximate filler content (wt%), other features, test temperature (°C), and Poisson's ratios. Polystyrene, acrylonitrile-butadiene-styrene, acetals-polyoxymethylene homopolymer, polyoxymethylene copolymer, modified polyphenylene ether/polyphenylene oxide, polycarbonate, polybutylene terephthalate, polyethylene terephthalate, liquid crystalline polymer, polyetherimides, polyamide-imides, polyimides, various nylons, polyphthalamide, polyarylamide, polyethylene, polytrimethylpentene, acrylics, thermoplastic copolyester elastomer, polytetrafluoroethylene, fluorinated ethylene-propylene, polyetheretherketone, polyethersulfone, polyphenylene sulfi de, polysulfone, and polyphenylsulfone are featured in this table.
