The ambient temperature of UHMWPE sheets should generally not exceed 80 °C. When the temperature of UHMWPE sheet is low, pay attention to the static time of the material in the warehouse to avoid freezing blocks. In addition, the UHMWPE sheet should not stay in the warehouse for more than 36 hours (please do not stay in the warehouse for viscous materials to prevent agglomeration), and materials with a moisture content of less than 4% can appropriately extend the time of rest.
The addition of UHMWPE fibers can greatly improve the tensile strength, modulus, impact strength, and creep resistance of UHMWPE sheets. Compared with pure UHMWPE, adding UHMWPE fibers with a volume content of 60% to UHMWPE sheets can increase the maximum stress and modulus by 160% and 60%, respectively.
