摘要

PA6/66, PA11, and PA12 are melt-compounded with phosphorus-based flame retardants (FR) OP 1312, OP 1314, and OP 1400 in sequence to study their influences on these polyamides in terms of thermal stability and flammability properties. While OP 1312, OP 1314, and OP 1400 have been commercialized specifically for the PA6 and PA66, this study will provide results on their effects to the three polymers above, with the hypothesis that OP 1400 will result improve the properties the most for all three polymers, because of its highest concentration of phosphorous. Different weight loadings, such as 10, 12.5, and 15 pph (parts per hundred) of each FR are blended using a twin-screw extruder with each polyamide to observe the correlation between a level of improvement and FR quantity. These results will help us to optimize the concentration of FR additives that yield the most effective solution with the least degradation on the mechanical properties for future applications. As a verification, scanning electron microscope (SEM) is used to observe any cracked surface on the formulations. Thermogravimetric analysis (TGA) is performed to evaluate each formulation's thermal stability and decomposition rate under combustion, and microscale combustion calorimetry (MCC) is used to quantify the flammability properties by measuring heat release rates. The study will provide valuable guidance for our FR polyamides research for additive manufacturing applications.
