Chapter 10. Engineering and Specialty Polymers

Engineering and specialty thermoplastics offer outstanding properties in one or more areas when compared with commodity thermoplastics such as polystyrene and polyolefins (see Chapter 9). Advantages may include high thermal stability or excellent chemical resistance, low creep compliance, and high tensile, flexural, and impact strength. Not unexpectedly, these properties come at a premium in price. In many cases, these polymers can be used as replacements for metals, particularly where a high strength-to-weight ratio is an important consideration, such as in automotive and aerospace applications.

The classification between engineering and specialty plastics is somewhat arbitrary. For purposes of ...
