Thermal properties

Dyneema® has a melting point between 144 and 152°C depending on the test method used. The maximum temperature for continuous use is 80°C. There is no brittle point found as low as -150°C, so the fibre can be used between that temperature and 80°C. Brief exposure to much higher temperatures will not cause any serious loss of properties.
