R45HT1G |
R-45HTLO
Polybutadiene Resin |
1
Gallon |
||
We've
chosen to offer R-45HTLO instead of R-45M for
a number of reasons. It has a slightly higher functionality, which results
in a higher crosslink density with the better room temperature curatives
(like E 744 described below), without resorting to other ingredients
that can adversely affect the cure chemistry. It also allows you to use higher
percentages of plasticizer without the propellant becoming too soft. OH values generally range from 0.80 to 0.86; the manufacturer's reported value is printed on the container label. |
||||
IDP8OZ |
Isodecyl Pelargonate Plasticizer |
8 oz |
||
IDP1G |
Isodecyl Pelargonate Plasticizer |
1 Gallon |
||
In
our opinion, Isodecyl Pelargonate (IDP) is the
best plasticizer for HTPB-based binders. Its low density, low viscosity,
low vapor pressure and cure retardant properties will give you a noticeable
improvement over DOA, DBP or whatever else you've been using. 10-35%
of the total binder percentage is the usual concentration. |

8 oz | Link | Link |
| E7441G | Desmodur
E 744 Isocyanate |
1 Gallon | Link | Link |
Desmodur
E 744 Isocyanate is an excellent room temperature
curative for HTPB. It provides plenty of pot life and good physical properties. If you've been using PAPI or Isonate 143-L you'll be amazed at the difference! Use at the 13.1%
concentration level with R-45HTLO with an OH value of .85 (hydroxyl
equivalent weight of 1176.5). For the mathematically challenged that's 86.9% R-45HTLO (at .85 OH value), 13.1% E 744 (with no plasticizer). Use the Binder Calculator on the "Resources" page to adjust the formulation for other OH values and plasticizer percentages. Pot life is 2 - 3 hours, cure time is 3 - 5 days at room temperature. |
||||
| CAO550G | CAO-5
Antioxidant |
40 grams | None | Link |
CAO-5 is an excellent antioxidant for HTPB resins, and should be used if your propellant will be not fired for 6 months or more. Use at the 1% level in combination with the polymer (i.e., 1% CAO-5, 99% R-45HTLO). |
||||
| FEO100G | Iron Oxide Catalyst |
100 grams | None | Link |
Iron Oxide is a moderate burn rate catalyst with a red color that increases the high pressure burn rate of APCP propellants. Our Iron Oxide is a sub-micron particle size that generates good burn rate enhancement with typical formulations. Typical concentration level is 0.5 - 3.0% of propellant weight. |
||||
| CRO100G | Chromium Oxide Catalyst |
100 grams | None | Link |
Chromium Oxide is a mild burn rate catalyst with a bright green color that improves the ignitability of APCP propellants. Typical concentration level is 0.5 - 2.0% of propellant weight. |
||||
| CUCR100G | Copper Chromite Catalyst |
100 grams | None | Link |
Copper Chromite is a proprietary blend of copper and chromium oxides, black in color, and is a moderate burn rate catalyst which finds use in endburning and medium-to-high burn rate compositions. Typical concentration level is 0.5 - 3.0% of propellant weight. |

20 pounds | None | Link |
A blend of rotary rounded 200 micron AP w/TCP and ground AP for high solids loading and castability. Intended for medium to fast burning rate propellant compositions (hazmat and extra shipping charges apply). |
||||
| APB400 | Ammonium Perchlorate 400 Micron Blend |
20 pounds | None | Link |
A blend of rotary rounded 400 micron AP w/TCP and ground AP for high solids loading and castability. Designed for slower burning propellant formulations (hazmat and extra shipping charges apply). |
||||
| APB400200 | Ammonium Perchlorate 400/200 Micron Blend |
20 pounds | None | Link |
A blend of rotary rounded 400 & 200 micron AP w/TCP and ground AP for high solids loading and castability. Intended for extremely high performance and high solids compositions (hazmat and extra shipping charges apply). |
