Flame Retardant Tapes


The Chemistry of Burning

Diagram (1) depicts how heat contributes to burning (combustion). It also illustrates the areas (X) where the chemical mechanisms, incorporated in the Polyonics FlameGard technology, actively help retard the burn cycle. Heat causes thermal degradation of polymers which in turn generates flammable gasses (fuel). Burning occurs when this fuel combines with oxygen in the presence of an ignition source. The process generates additional heat and gases creating a self-sustaining burn cycle.

Diagram (2) illustrates the role temperature plays in accelerating this cycle. At temperature (T1) very few of the molecules (area under the curve) have enough energy (activation energy Ea) to burn. Adding more heat raises the temperature to (T2) causing more molecules to have enough energy to become fuel and burn.

At (T3), the majority of molecules have become fuel and a sustainable fire is likely. Conversely, if the temperature can be lowered from (T3) to (T1), the fire will self extinguish.

Polyonics employs resins and polymers that are dimensionally stable and don’t generate significant amounts of flammable gasses when exposed to heat and flame. In addition, upon initial combustion, the fire retardant tapes create a char layer (Diagram 1) that acts as a heat shield (physical mechanism) slowing the rate of thermal oxidation and reducing thermal degradation.

These design features combine to create the flame retardant mechanisms to;

  • Reduce heat.
  • Remove oxygen.
  • Reduce the concentration of gasses.
