HTPB (Hydroxy-Terminated Polybutadiene W/1% Antioxidant)

Hydroxy-Terminated Polybutadiene (HTPB) is a reactive liquid prepolymer widely used as a binder, fuel, and curable polymer base in solid rocket propellants, polyurethane elastomers, coatings, and adhesives.

This formulation includes 1% antioxidant additive, providing improved oxidative stability and extended shelf life without affecting cure characteristics or performance. It is suitable for both research and industrial applications where controlled hydroxyl functionality and consistent viscosity are critical.
