Use of Antimony Trioxide

ATO provides unique properties not easily obtained through other products when applied in a variety of industrial processes: 

 

·    Increasing Fire Resistance of Materials:
Ensuring high levels of fire safety for the individual citizen in their home as well as in public places such as cinemas, underground trains and airplanes, has led to international safety standards requiring inherently flammable materials to be treated with flame retardant chemicals. ATO greatly increases flame retardant effectiveness when used a synergist in combination with halogenated flame retardants in plastics, paints, adhesives, sealants, rubber and textile back coatings.
 

ATO ensures a high level of resource efficiency and compliance with stringent fire safety standards. For example, it enables the use of certain plastics in consumer products such as computer housings and TV sets that might otherwise pose a great fire hazard.
 

·    The Leading Catalyst for Manufacture PET Plastics:

ATO is the major catalyst for the production of PET plastic used in the packaging of mineral water and soft drinks. PET is one of the best materials for plastic bottles, with a history of safe use by millions of consumers every day.  ATO’s safety in the production of PET bottles has been confirmed by the World Health Organisation (2003) and the European Food Safety Authority (2004). The use of ATO as a catalyst in PET bottles does NOT impact the safety of the beverages.

 

Other uses of ATO include:

·   as a clarifying aid in certain glasses,

·   as a coating used on certain grades of TiO2 pigments,

·   as a component in the manufacturing of complex inorganic coloured rutile pigments and

·   as an opacifier in cast iron bath and sinking enamelling.
