Uhmwpe working temperature
Webtemperature of about 180°F. However UHMW-PE has a high coefficient of thermal expansion, which can cause it to dramatically change dimensions over temperature … UHMWPE is a type of polyolefin. It is made up of extremely long chains of polyethylene, which all align in the same direction. It derives its strength largely from the length of each individual molecule (chain). Van der Waals forces between the molecules are relatively weak for each atom of overlap between the molecules, but because the molecules are very long, large overlaps can exist, a…
