Tm of hdpe
WebDec 1, 2024 · Tm and the heat of fusion (ΔHm) were obtained from the thermograms during the second heating. The values of ΔHm were used to es-timate the crystallinity degree (Xc). The degree of crystallinity (Xc) of the PLA and HDPE component was determined from the following equation [14] [15] Table 1. Biocomposite size 3.2. WebMelting temperature (Tm) of high-density polyethylene (HDPE) is approximately 120 °C and the Tm of nylon-6 is approximately 220 °C. Both are structurally not much different, but the Tm difference between them is about 100 °C. What is the origin of this difference? This problem has been solved!
