“…The mixture is then placed in a mold and the exotherm from the resin cure causes the expandable particles to foam and squeeze the resin or foamed matrix to the surface of the molding. A typical example is Voraspan, expandable polystyrene in a flexible polyurethane foam matrix (122). These foams are finding acceptance in cushioning applications for bedding and furniture.…”

This article is concerned with the general theory of expansion, manufacturing processes, properties, and applications of foamed (cellular) plastics. The high strength‐to‐weight ratio, excellent insulating properties, and cushioning properties of cellular plastics have contributed to the development and growth of the broad range of cellular plastics in use. The total usage of foamed plastics in the United States has risen from 441 thousand metric tons in 1967 to 1.6 million metric tons in 1982 and has been projected to rise to about 2.8 million metric tons in 1995. The manufacturing processes for cellular polymers are described in terms of three classified methods based on the cell growth and stabilization processes. The properties of cellular plastics including mechanical, thermal, electrical, and environmental aging properties, are summarized. A general discussion is given on the properties of cellular plastic necessary in many applications such as the comfort cushioning, thermal insulation, packaging, structural components, buoyancy, electrical insulation, and space‐filling markets. A brief discussion is also given on the process economics, raw materials, and energy considerations for the commercial products of primary importance.

“…Figure 89d shows the relative energy absorption of the three materials tested, indicating the composite foam as a compromise between polystyrene and semi-rigid urethane foam. 114 It was concluded that, on the typical response curve for a compression test, where the area contained within the hysteresis loop shown in Figure 90 is directly related to the energy absorbed, three performance parameters can be defined: the specific energy absorbed at maximum strain, the relative energy-absorption ratio, and the maximum stress. The total energy absorbed at maximum strain is the sum of areas A and B.…”

This article examines both styrene plastics, including such commodity styrenic resins as general‐purpose polystyrene, high impact polystyrene, styrene–acrylonitrile, and acrylonitrile–butadiene–styrene, and specialty resins such as ionomers, styrene derivatives, and tactic polystyrenes. Topics discussed include styrenic plastic properties such as stress–strain, creep, stress relaxation, fatigue, impact strength, surface appearance, and melt properties, as well as rubber modification and glass filling of styrene plastics. Styrene plastics manufacturing processes and the chemistry of styrene polymerization are both described, the former with an emphasis on the most widely used continuous free‐radical reaction designs, the latter mainly on the industrially important free‐radical mechanism; other mechanisms by which styrene can be polymerized, ie, anionic, cationic, and Ziegler‐Natta, are also mentioned. The description of free‐radical polymerization of styrene covers spontaneous initiation, chemical initiators, chain‐transfer agents, and living free‐radical polymerization. Copolymerization of styrene with other monomers is also discussed. Other topics covered include fabrication processes, ie, injection molding, extrusion, thermoforming, and blow molding; additives; economic aspects; characterization techniques; health and safety issues; foamed polystyrene; and environmental issues, including recycling.
