WebDec 19, 2024 · The flame-retardancy of composites was studied by the limiting oxygen index (LOI) and UL-94 test. The LOI values of EP–DSD composites increased from 30.7% for a content of 3 wt % to 35.4% for a content of 9 wt %. When the content of DSD reached 6 wt %, a V-0 rating under the UL-94 vertical test was achieved. SEM photographs of … From lowest (Least flame-retardant) to highest (Most flame-retardant): • HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm • V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
