CAS 69102-90-5 — HTPB (POLI BDR45 HT BAJO) ESPEC. WS23148C (TIPO II)

HTPB (hydroxyl-terminated polybutadiene) is a synthetic rubber polymer widely used in aerospace, adhesives, and composite applications for its high energy density and durability. This specific grade, **POLY BDR45 HT LO (WS23148C, Type II)**, is a low-molecular-weight, hydroxyl-terminated polybutadiene designed for propellant and casting resin formulations. It features a hydroxyl value of 0.45–0.55 meq/g, cis-1,4 content of ≥40%, and a viscosity of 4,000–8,000 cP at 25°C. Non-hazardous under standard conditions, it requires ambient storage. Molekula supplies POLY BDR45 HT LO from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
