Ammonium Perchlorate (AP) — 90μm Grade
CAS Number: 7790-98-9
Ammonium perchlorate (NH₄ClO₄) 90μm fine particle grade is a high-purity solid oxidizer for composite solid rocket propellant formulation. Purity ≥98.8% with tightly controlled particle size distribution centred at 90μm (fine fraction), enabling high oxidizer packing density and tunable burn rates in HTPB, PBAN, and CTPB binder systems. Produced under strict process control with low iron, low chloride, and minimal moisture to prevent propellant sensitivity drift. ⚠️ Export license required — inquire for compliance documentation.

Applications
- Composite solid rocket propellant (CSRP) oxidizer in HTPB and PBAN binder systems
- Gas generators for aircraft ejection seats and emergency systems
- Automotive airbag inflator pyrotechnic charges
- Pyrotechnic formulations: illuminating flares, signal compositions
- Solid propellant research and ballistic testing
Key Features
- High purity ≥98.8% NH₄ClO₄ — minimises inert ash and propellant density loss
- Fine 90μm particle grade — optimised for high-energy composite propellant formulations
- Ultra-low iron ≤0.0036% — prevents catalytic decomposition and shelf-life degradation
- Controlled TCP 0.15–0.22% — consistent ballistic performance batch-to-batch
- Export compliance documentation available upon request
