WebNov 10, 2024 · High-density polyethylene (HDPE) is a thermoplastic polymer with ethylene as its monomer unit. The hydrocarbon ethylene, often known as ethene (IUPAC nomenclature), has the formula C 2 H 4. PEHD (polyethylene high density), alkathene, and polythene are all terms for high-density polyethylene. WebJan 1, 2024 · The peak melting temperature (Tm) and % crystallinity of HDPE were reduced to 133.5 and 43.4% respectively in HDPE-25FB blend, indicating reduction in crystallinity by the addition of FB. However, the crystallization thermogram of HDPE-FB had dual peak (not shown here) indicating possible incompatibility with matrix phase at molecular level.
