The different conclusion may be due to the fact that we did not normalize for other influences, such as body mass index (BMI), when investigating the effect of individual characteristics on the distribution of metabolites in urine. Gao et al. (2020) normalized the BMI of the population ...
Ultimately, BFRs slow or prevent the spread of flames [[4], [5]]. Most BFRs decompose between 280 and 900 °C, which aligns with that of common plastics. By taking advantage of the relatively low bond energy between CBr, BFRs can effectively capture free radicals generated during plastic ...
(talc, wollastonite, mica, etc.), metal hydroxides, and other natural mineral materials, play a crucial role in enhancing the flame retardancy of epoxy resins. This chart compares the Limiting Oxygen Index (LOI) values of different types of natural flame-retardant mineral materials,Figure 10. ...
