This unique introduction covers both low- and high-density thermoplastic foams in an easy-to-follow style, avoiding excursions into the theoretical aspects of foam processing. The book includes information on materials and their properties and all major foam extrusion processes. A considerable part of the volume is comprised of a comprehensive troubleshooting guide, designed especially for newcomers, but also invaluable to seasoned foam extrusion practitioners.

From the Preface: “This primer is specific to synthetic thermoplastic foams and to foams that are extruded. Foams offer unique advantages over traditional materials and unfoamed materials. They have unique insulating properties, buoyancy, and outstanding strength-to-weight ratios, among other attributes. Foam processing and product performance strongly depend on the material and processing characteristics of the unfoamed thermoplastic polymer...”

Target Audience: Newcomers and seasoned professionals involved in extruded foam production.
