Web1 Jan 2011 · These crystalline and amorphous entities of UHMWPE may be visualized using TEM and SEM. When UHMWPE is heated beyond its glass transition temperature, at about 90-100ºC, the amorphous regions become mobile and the crystalline regions begins to melt. The melting point of UHMWPE is about 134ºC. Web31 Aug 2024 · UHMWPE is not appropriate for high-temperature applications since it has a lower melting point (297° to 305° F) than several popular polymers. It also has a low coefficient of friction, which may be a disadvantage depending on the application.
