DOA - Dioctyl Adipate
Used as a plasticizer for HTPB compositions, it makes the end product softer, more flexible, and reduces the glass transition temperature (temperature at which the resin becomes glass-like, a bad thing). This additive makes HTPB compositions easier to process since the plasticized mixture is of a lower viscosity than a mixture without. Compatible with both HTPB and PBAN.8 Ounces - $12.00
Silicone Oil
Silicone Oil is used in motor making and as an additive for bipropellant motors.For composite motors, one or two drops per kilogram of mixture is sufficient to allow smoother, easier blending compositions.
For bipropellant mixtures, 1% by volume in the fuel helps reduce heat flux by up to 60%.
From John Clark in "Ignition!"
"Oxygen motors generally run hot, and heat transfer to the walls is
at a fantastic rate. This had been a problem from the beginning,
even with regenerative cooling, but in the spring of 1948 experimenters
at General Elextric came up with an ingenious fix. They put 10 percent
ethyl silicate in their fuel, which as, in this case, methanol. The
silicate had the happy faculty of decomposing at the hot spots and depositing
a layer of silicon dioxide, which acted as insulation and cut down the
heat flux."
