Processing of ultrahigh molecular weight polyethylene

摘要

AbstractThe extent of recrystallization of nascent UHMWPE powder is easily measured by calorimetry. Melting and recrystallization of nascent UHMWPE at 140°C can be suppressed by compression molding. Crystals of UHMWPE prepared from dilute solution show a peak melting temperature of 140°C and exhibit crystallinity up to 75.5 depending on crystallization temperature. Large changes in crystallinity result from drawing single crystal mats or compression‐molded fi
