Pool Burning of Silicone Fluids (NISTIR 5499)



R Buch, Anthony Hamins, John R. Shields, P. Borthwick, R T. Baum, Marc R. Nyden, Takashi Kashiwagi


Siloxane fluids have a number of industrial applications including use as transformer fluids. The objective of the present study was to improve our understanding of the burning of siloxane fluids. The fluids studied are octamethylcyclotetra siloxane, [(CH3)2SiO]4 which is known as D4, and trimethylsily end-blocked polydimethyl siloxane, [(CH3)3Si-O[-Si(CH3)2-O]n-Si(CH3)3 ], where n indicates the polymer chain length and the number of silicon atoms in the molecule. These fluids are ranked by viscosity which is related to the average polymer chain length as shown in Table 1.
