Three different types of plasticized PVC compositions were investigated: clay filled with 52 phr plasticizer (and containing antimony trioxide
as flame-retardant synergist); clay filled with 50 phr plasticizer (without antimony trioxide
); and unfilled with 83 phr plasticizer (i.
Modification of epoxy material by antimony trioxide
is more effective than modification using molybdenum trioxide, because it affects a much larger extent reducing the heat release rate of epoxy flooring composite; yet, unfortunately, it increases the smoke release intensity by the tested material in analysed heat exposures.
A comparative analysis of the influence of both tested additives on the studied polyester material, based on the obtained thermogravimetric results, demonstrated antimony trioxide
to be a more effective modifier of the flammable properties of the products, based on Polimal 1033 APy rather than molybdenum trioxide increasing its thermostability.

From the WAXD patterns the ratio of elemental antimony to antimony trioxide
was easily estimated.
The Nokia X7 is free of PVC, free of nickel on the product surface, brominated and chlorinated compounds, and antimony trioxide
One of the materials they will produce is antimony trioxide
, which is currently used as a flame retardant in a wide range of products, ranging from textiles and furniture to plastic covers designed to reduce the risks caused by car and aircraft engine fires.
The proposed move comes on the heels of its announcement last October that it plans to establish an Antimony Roaster Project at the free zone with a capacity to process around 40,000 tonnes per annum of concentrates, yielding an estimated 20,000 tonnes of metallic antimony or 25,000 tonnes of antimony trioxide
of Indianapolis announces that, effective for shipments after August 19, 2002, where contracts allow, the company is increasing the price of all grades of antimony trioxide
In order to meet the requirement, in current Chinese market, flame-retardant PP is produced by combining organic substance containing halogen with antimony trioxide
Nokia scores very well on toxic chemical issues, launching new models free of PVC (polyvinyl chloride) since the end of 2005 and aiming to have all new models free of brominated flame retardants (BFRs) and antimony trioxide
(a chemical flame retardant) by the end of 2009," Greenpeace said in its report.
announces that, effective for shipments after August 1, 2002, where contracts allow, it is increasing the price of all grades of antimony trioxide
