A quantitative measurement method with FT-IR was proposed for a thermal degradation analysis of nitrile-butadiene rubber (NBR). An NBR film was prepared as a model sample on a barium fluoride (BaF2) crystal plate, which was subjected to a heat treatment. The absorbances of various functional groups were measured directly by FT-IR after thermal degradation at high temperatures. By measuring the ...

The commercial aviation sector is seeking to reach net zero CO2 emissions by 2050, with sustainable fuel (SAF) being the most important lever. However, SAF currently limited ASTM specifications a maximum of 50%v blending conventional jet fuel. One reason for current blend limit motivation maintain o-ring swelling consistent 100% petroleum This work explores relationships between components, mod...
