There are three methods for flame retardance: vapor phase inhibition, solid phase char formation, and quench and cool systems that work by removing or reducing heat, fuel or oxygen.

solid phase char formation

Vapor Phase Inhibition

This approach works by removing flammable gaseous chemicals from the burning plastic. Chlorine and bromine based chemicals and polymers are used as the active flame retardants with MAT’s FLAME DEFENSE SERIES blends FD320, FD335, FD373, FD409, and FD415 antimony trioxide replacements. Or with antimony trioxide using MAT’s FDAO.

vapor phase inhibition

Solid Phase Char Formation

Flame retardants are designed to build up a barrier layer, once the fire has begun thus eliminating the fuel by char and protects the plastic. MAT’s SMOKE DEFENSE blends SD775, SD808, SD845, SD890, and ammonium octamolybdate SDAOM work in this way and act as powerful smoke suppressants. Zinc Borate, Zinc Stannate, and Zinc Hydroxy Stannate products also work this way.

quench & cool systems

Quench & Cool Systems

Utilize hydrated minerals because of the endothermic water release process that occurs when the system is heated. In the presence of fire, the hydrated minerals release water molecules that cool the polymer and suppresses the combustion process. MAT’s alumina trihydrate (ATH) and magnesium hydroxide work in this way.
