We’ve decided to release our old chemicals catalog for HPR and AM/EX rocketry supplies and items. If you need powdered oxidizers (potassium and ammonium nitrate) especially, please check out our offerings here or by selecting the DIY Motor Kit & Supplies tab.
Prices and shipping are better than reasonable and the product in a beautiful crystalline fine flake especially prepared and formulated for serious rocket propulsion. Price breaks in quantity. What we use in our large birds, but perfect for HPR or AM/EX.
