How to improve the compression performance of UHMWPE sheet

First, for UHMWPE sheet, the polyethylene liner polyethylene liner to improve impact resistance, impact strength and its associated molecules, the molecular weight of less than 2 million, with the increase in molecular weight, the impact strength increased about 2 million, reaching a peak,
Then, the increase in molecular weight and impact strength. This is due to the molecular chain is very disturbing effect of crystal lamps, in the amorphous region can absorb the impact energy of a large macromolecules. The method measured values ​​astm-d256 impact strength plastic, such as ultra high molecular weight polyethylene.
In short, the impact resistance of polycarbonate can be divided into shock comparable to UHMWPE at room temperature, used in engineering plastics. UHMWPE sheet even at low temperatures, even in the liquid and the temperature of the gas - 269oc, can also better impact resistance, the excellent temperature properties, so that extends into the ultra-high molecular weight polyethylene in the application of cryogenic engineering.
