Description

Antimony Pentoxide Sol CAS NO 12712-36-6 is a stable colloidal dispersion of antimony pentoxide in water, offering superior performance over traditional powdered forms. This product is engineered to provide exceptional flame retardant and smoke suppressant properties in a convenient, easy-to-handle liquid form. It is a critical material for manufacturers in the plastics, textiles, and coatings industries seeking to enhance the fire safety of their products without compromising on processing or final material properties.

Application

• As a highly effective flame retardant and smoke suppressant in PVC, polyolefins, and engineering plastics.
• In the formulation of fire-resistant coatings and paints for textiles, wood, and construction materials.
• For the production of flame-retardant masterbatches and compounds used in wire & cable insulation and electronic components.
• As a synergist with halogenated flame retardants to improve efficiency and reduce overall additive loading.
• In the manufacture of fireproof textiles and fabrics, including upholstery, curtains, and protective clothing.
• For catalytic applications in certain organic synthesis and petrochemical processes.
