“…This resulted in the formation of char, as a weight plateau was observed between 350 and 550°C 19,44 . Additionally, the second decomposition peak (T max2 ) was attributed to evaporation and/or dehydration of phosphoric acid to form P 2 O 5 and P 4 O 10 as well as decomposition of the previously formed char 43–46 . As shown in Figure 6 and summarized in Table 4, the weight loss of the APP/5PBS‐ g ‐GMA/PBS composite at temperatures ranging from 600 to 800°C (ΔW) was higher than that of the WHF/5PBS‐ g ‐GMA/PBS composite.…”

“…Their initial decomposition temperatures were significantly lower than that of neat PBS due to the lower starting decomposition temperatures of APP and WHF. Besides the peak corresponding to PBS decomposition at around 350°C, the DTG thermogram of the WHF/5PBS‐ g ‐GMA/PBS composite revealed an additional peak corresponding to cellulose decomposition between 320 and 370°C 43 . The DTG thermogram of the APP/5PBS‐ g ‐GMA/PBS composite revealed two decomposition peaks at 350°C (T max1 ) and 615°C (T max2 ).…”

In this study, water hyacinth fiber (WHF) was used as a carbon source in combination with ammonium polyphosphate (APP) to formulate an environmentally friendly intumescent flame retardant for poly (butylene succinate) (PBS) composites. Glycidyl methacrylate grafted poly (butylene succinate) (PBS-g-GMA) was prepared via a reactive melt grafting reaction to serve as a compatibilizer for WHF/APP/PBS composites. Effects of incorporating APP and WHF, and PBS-g-GMA on mechanical properties, thermal properties and flame retardancy of PBS composites were investigated. Results showed that the addition of PBS-g-GMA greatly improved tensile strength, flexural strength and crystallization rate of WHF/APP/PBS composites. According to UL-94 and limiting oxygen index (LOI) tests, the presence of 15 wt% WHF, 30 wt% APP, and 15 wt% PBS-g-GMA enabled the WHF/APP/15PBS-g-GMA/PBS composite to achieve a V-0 rating and the maximum LOI value of 29.2%. Char residue analysis revealed that the combination of APP and WHF promoted the formation of an expanded char layer, whereas the addition of PBS-g-GMA induced the formation of compact, highly graphitized residues. Findings will contribute to the development of biodegradable flame-retardant polymer composites for engineering applications.

Plasticized polyvinyl chloride (PVC) burns easily and generates a lot of smoke during combustion. In order to improve the comprehensive performance of plasticized PVC, hydrogenated nitrile‐butadiene rubber (HNBR) with different degrees of saturation (88%, 94% and 99%) were melt blended with plasticized PVC. Compared to the plasticized PVC without HNBR, the glass transition temperature decreased from −10.6 to −26.0°C, the initiation temperature for thermal degradation increased from 272 to 281°C, the elongation at break enlarged from 316% to 477%, and the permanent set dropped from 72% to 61% when HNBR was added to plasticized PVC at a ratio of 30 parts per hundred parts of resin. However, this resulted in a weakening of tensile strength of the plasticized PVC. Additionally, in the cone calorimetry test, the total smoke production of the PVC/HNBR blends (from 18 to 22 m2) was lower than that of the PVC control (23 m2) and the time to ignition was increased from 26 to 32 s. As a result, PVC/HNBR is expected to gain popularity in the rubber and plastic pipe, wire, and cable sheathing industries.Highlights Plasticized PVC improves thermal stability by melt blending with HNBR. All PVC/HNBR samples have excellent low‐temperature resistance. The addition of HNBR decreases the burning smoke density of plasticized PVC.
