Elastomeric Materials for Acoustical Applications
Abstract
A background discussion of polymer viscoelasticity is given. Methods of polymer characterization are discussed. Factors in the compounding and vulcanization of elastomeric materials which affect end-product performance are also discussed. General information and cure systems are discussed for a number of different classes of rubber materials. Dynamic mechanical properties of a number of elastomeric materials are graphically presented. Compounding recipes and cure conditions are included, as well as the static physical properties. References to standard test methods (ASTM) are included where applicable. Indices containing names of suppliers of elastomeric materials and adhesives, as well as generic and trade-name cross-indexing, are also incorporated into this work. Additionally, an appendix on acoustical coupling fluids is included. This lists many of the fluids currently in use. Physical properties of interest, such as dielectric constant and electrical resistivity, as well as thermodynamic properties (where available) are included. Keywords: Adhesion; Butyl rubber; Chlorobutyl rubbers; Ethylene-propylene-diene-monomer; Fluorocarbon rubber; Natural rubber; Neoprenes; Acrylonitrile rubber; Polyurethanes.
