Sectors
Plastics & Polymers, Building & Construction
Sodium Pyroantimonate is a high-purity inorganic compound serving as a premier glass fining agent for optical and photovoltaic applications. It acts as a powerful oxidizer to eliminate bubbles and ensure superior clarity in solar glass and cathode ray tubes. Functioning as a highly effective flame retardant synergist, this white powder enhances the thermal resistance of engineering thermoplastics such as PET and PBT. It is frequently utilized in high-performance polymer formulations where minimal pigmentation impact is required. This technical-grade material exhibits excellent chemical stability and controlled particle size for uniform dispersion in industrial batches. It is a critical component in the production of specialized ceramics and high-definition display glass.  

SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Sodium Pyroantimonate (CAS 12507-68-5) to customers in more than 40 countries.
