They have improved resistance to high temperatures [1] [2] and chemicals and even withstand environments where Oxygen-Plasma are present for many hours. Certain grades have a maximum continuous service temperature of 327 °C (621 °F).
Polyolefin tubes, the most common kind, [8] have maximum continuous-use temperatures from -55 to 135 °C, and are used by the military, aerospace and railway industries. They are flexible and fast-shrinking, and manufactured in a wide range of colors (including clear), which can be used for color-coding wires.
The name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition (although this is not their only feature, as it can be seen above). The term "polymers" is often used instead of "plastics" because both terms are used as synonyms in the field of engineering.
These properties are influenced by a 400-450 °F (204-232 °C) continuous use temperature and a glass transition of 500 °F (260 °C).

Excellent resistance to solvents and chemicals. Low application temperature, suitable for heat-sensitive substrates. Heat-resistant after curing, with service temperatures generally from −30 °C (−22 °F) to 150 °C (302 °F). Ink-solvent resistant. Often used in bookbinding, automotive, aerospace, filter and plastic bag applications.
