... are easier to thermoform, many of the thermoset foams are only lightly crosslinked and exhibit some formability. Core densities normally range from about 2 to 40 pcf (32 to 640 kg/m 3 ). The most widely used structural foams are summarized in Table 9.3 . It is important to thoroughly understand the chemical...

...% of forming uses blow molding (10% of all plastics), thermoforming, compression molding, coating, laminating, rotational molding, and all others. However, injection molding is the most important, and, except for compression or transfer molding of thermosets, is usually the most accurate in maintaining...

... be thermoformed into structural shapes by simply reheating to the processing temperature. Thermosets, due to their highly cross-linked structures, cannot be reprocessed and will thermally degrade and eventually char if heated to high-enough temperatures. Many thermoplastics are polymerized by what is called...
