Composition Zylon® PBO is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet spinning process.

CATEGORY DETAIL EC Number 215-175-0 CAS Number 1309-64-4 Name Subclass 1 Antimony Trioxide (ATO) Structural Formula CHEMICAL IDENTITY PROPERTY DETAIL Physical State Solid Form Powder Color White Odor Odorless Melting Point 656°C Boiling Point 1425°C Bulk Density 5.20 g/cm3 Water Solubility Slightly Soluble PHYSICAL/ CHEMICAL PROPERTIES HEALTH EFFECTS HUMAN HEALTH SAFETY ASSESSMENT Consumer It is very unlikely that consumers would be exposed to ATO in its concentrated form because it is only sold for industrial use to make polymers and other products and is not sold directly to consumers.

Both paperboard and multilayer polymers restrict design freedom, so the final packaging is often less than ergonomic.
