Flame Retardant Mechanism of Antimony Trioxide

Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. 

Antimony trioxide reacts with halogenated compound and creates the chemical compounds, which generate the flame retardant function, through the following process.


1. Stop action of thermal de-composite chain reaction under gas phase (Radical trap effect) 

2. Sealing action against oxygen under gas phase (Air sealing effect) 

3. The formation of carbonaceous char under the solid phase (Air sealing and adiabatic effect) 

Novista Group supplies equivalent of FP-2100JC, FP-2200S, FP-2500S, Exolit OP1230, OP930, OP1312, OP1314 to global market.
