Composite
Propellants
Composite propellants are heterogeneous mixtures of fuels and finely divided oxidizers bound by a viscous binder. Typical applications include solid rocket motors, satellite kick stages, and booster motors for cruise-missile launches.

Ammonium Perchlorate
NH₄ClO₄ (ammonium perchlorate) is sold in 90, 200 and 400 µm particle sizes (other sizes possible). When blended with a binder and fuels like powdered aluminum, it can burn continuously even at much lower-than-atmospheric pressures, making it a common choice for rocket propellants.

Dimeryl Diisocyanate (DDI)
Dimeryl diisocyanate (DDI-1510) is the preferred curative for low-molecular-weight HTPB polymer propellant formulations. This high-molecular-weight isocyanate features a 36-carbon aliphatic backbone, low toxicity, and low water sensitivity, and it also acts as a burn-rate catalyst

Hydroxyl Terminated Polybutadiene (HTPB)
HTPB is an outstanding binder for solid rocket propellants, delivering a robust yet elastic fuel matrix. It is also used as the solid component in hybrid rockets paired with nitrous oxide (N₂O). The R-45M grade of HTPB is the premium military binder, offering low-temperature flexibility, superior metal adhesion, and excellent filler dispersion.
