HOW IT WORKS - During manufacture of the fiber, a proprietary organic phosphorus
compound is incorporated into the polyester polymer. The result is Avora® FR with a
lower melting point than regular polyester. This makes it difficult for combustion to
take place as the fiber melts and shrinks away from flames. The phosphorus
component prevents melting drips from occurring and prevents further burning by
self extinguishing.
Combustion gases from Avora®FR fabrics are simular to regular polyester and are
composed primarily of carbon monoxide (CO), carbon dioxide (CO2) and water vapor,
as well as small quantities of organic compounds which contain primarily aldehyde
and keto groups. Gases such as hydrochloric acid (HCI), dioxins, hydrogen cyanide
(HCN), nitrous oxides (NO) or sulfur dioxides (SO2) are not present. The Avora FR
polymer contains no brominated compounds.
