FLAMTARDTM ANTIMONY-FREE FLAME RETARDANT SYNERGIST
Based on zinc hydroxystannate chemistry, Flamtard™ H is thermally stable up
to 220°C and is the synergist of choice for many low temperature processing
polymers such as PVC. The zinc and tin components in the product act in
the gas and condensed phase to provide a dual mode of action for inhibiting
the propogation of flame and smoke. Flamtard™ H can be used to replace
antimony flame retardants and is typically used at low concentrations in
combination with a halogen source or other flame retardant additive.
Based on zinc stannate chemistry, Flamtard™ S is an anhydrous product that
is stable above 400°C and recommended for high temperature processing
polymers. Alongside the synergistic ability of providing flame protection and
smoke suppression properties, Flamtard™ S is also an acid scavenger and
as such provides anti-corrosion functionality in systems where free acid is
generated during polymer processing. Flamtard™ S can be used to replace
antimony flame retardants and is typically used at low concentrations in
combination with a halogen source or other flame retardant additive.
A mixed metal (hydroxy)oxide that can be used as a cost-effective, nonhazardous
replacement of antimony-based flame retardant synergists in PVC
formulations. Flamtard™ X can be used at low concentrations in combination
with a halogen source or other flame retardant additive.
