For medium- and high-density polyethylene the melting point is typically in the range 120 to 130 °C (248 to 266 °F). The melting point for average commercial low-density polyethylene is typically 105 to 115 °C (221 to 239 °F). These temperatures vary strongly with the type of polyethylene, but the theoretical upper limit of melting of ...

Its melting point is around 130 to 136 °C (266 to 277 °F), [8] and, according to DSM, it is not advisable to use UHMWPE fibres at temperatures exceeding 80 to 100 °C (176 to 212 °F) for long periods of time. It becomes brittle at temperatures below −150 °C (−240 °F). [9]
Melting points (in blue) and boiling points (in pink) of the first eight carboxylic acids (°C). For most substances, melting and freezing points are approximately equal. For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2]

Interest in the material in the 1950s arose from its high melting point and tensile strength, making it more desirable than the more common form of polyethylene. For example, the medical community in 1958 was eager to use Marlex 50 crystalline polyethylene which softens at 260 °F (127 °C).
