The thermal stabilities and flame retardancy of FR-PA66 were measured using thermogravimetric analysis (TGA), a thermogravimetric infrared instrument (TG-IR), the limiting oxygen index (LOI), the horizontal and vertical combustion method (UL-94), and a cone calorimeter.

2024年11月4日 · 采用热分析-红外-质谱联用仪（STA-FTIR-MS）和热裂解/气相色谱-质谱联用仪（Py/GC-MS）对聚酰胺56（PA56）与聚酰胺6（PA6）、聚酰胺66（PA66）的热分解行为进行了比较研究。 旨在阐明PA56与PA6、PA66在热分解过程中表现出的差异性及热裂解机理特点。 通过阿伦尼乌斯（Arrhenius）方程计算反应活化能（Ea），并进一步通过热裂解实验对PA6、PA66、PA56的热降解产物进行分析。 结果表明：PA6、PA66、PA56在氩气中的热降解过程均为一 …

In this study, the carbonization-in-nitrogen method (CI... ... analysis (TGA) was conducted on the thermoplastic composite samples to determine an optimized temperature to carbonize the samples...

2017年3月7日 · The best hit, “PA66-GF30_TGA”, is a TG database measurement on exactly the same material as that of the measurement of the sample “PA66-GF30_STA”. Obviously, the database search revealed many further TG curves of various polymer types which have also a high similarity to the TG curve of the polymer sample “PA66-GF30_STA” (see Fig. 4 ...

2015年10月1日 · The thermal molecular degradation of polyamide 66 (PA 66) doped with (partially supported) metal oxide particles (Fe 2 O 3, ZnO, Al 2 O 3) was investigated qualitatively and quantitatively using common analysis techniques like thermogravimetry coupled with IR-spectroscopic evolved gas analysis (TGA-FTIR). Using pyrolysis coupled with gas ...

2016年4月4日 · The results of TGA and DSC demonstrated that the thermal stability of PA66 was improved after incorporation of BNPO, NENP, DPPD, and MCPO. The flame retardancy of PA66 reached V-0 and crossed 27% (LOI), which meant that the FR-PA66 was not inflammable.

2019年6月15日 · The TGA results indicated that the initial and peak decomposition temperature of PA66 composites increased by 47 °C and 34 °C in the presence of 8 wt% MCPO, respectively. Moreover, the heat release rate and production of smoke decreased, as observed by the HRR and TSP results, and gas phase flame retardant mechanism was confirmed by the cone ...

2024年10月20日 · The HDTs of PA66/CST and PA66/CRT at 50 % TiO 2 addition respectively increased by 70 % and 207 % compared to pristine PA66, suggesting the superior capability of RT to ST on improving the heat resistivity of PA66.
