《塑料技术手册 发泡成型·压延成型（1 影印版）》：

Polyethylene，polyurethane， and polystyrene are the most commofoams； however， polypro— pylene （PP） foams caprovide favorablc properties at a lower material cost.PP is stiffer thaPE and performs better iload bearing and structural applications.The low glass—transitiotempera— ture of PP compared to PS provides increased flexibilitv and impact strength （chapter 1）.Use of PP foams includes packaging， automotive， insulation， and protectioof underground pipe.

It is important to know iadvance what foam properties will be required for a particular application.As with other plastics or any material， it is not enough to be told that a material is plastic foam with remarkable properties.The following review oexamples of different plastics used includes preliminary informatiooprocesses and applications.It starts by reviewing the subject of structural foams and reinforced plastic foams.

STRUCTURAL FOAM

Structural foam is a term originally used for cellular thermoplastic articles with integral solid skins and possessing high strcngth—to—weight ratios （Table 8.25）.Eventually， the term covered high— density rigid cellular plastics strong enough for structural applications.As aexample， thermoset foams， such as polyurethane， are frequently referred to as structural foams.Igeneral， a structural foam cabe made from virtually any high molecular weight thermoplastic organic polymer and will have a cellular core and aintegral skioall sides.The skiis relatively nonporous irelatioto the cellular core.
