AF-7720 - High temperature capable UHMWPE, PEHUD.
AF-7720 maintains all the advantages of standard UHMW-PE as the long carbon
chain is preserved, wear resistance in intact.
But is capable of operating at temperatures as high as 120°C while maintaining
mechanical properties and dimensions stability, this has been documented in
several tests at customers, as consequence the material has been well embraced
in the marked.

BACKGROUND
The superb wear resistance and high-pressure performance of UHMW-PE has
been known for some time.
The main drawback of UHMW-PE is the limited temperature capability, mechanical properties degrade fast as temperature rises towards to recommended maximum of 80°C.
