Ammonium Perchlorate (AP) — 90μm Grade
Número CAS: 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.
