Fire retardancy of a new polypropylene-grafted starch
Reaction to fire of several intumescent Gaialene formulations (Gaialene is a polypropylene-grafted starch) was investigated by mass loss cone calorimeter. Formulations exhibiting promising results were optimized by a design of experiments using mass loss cone calorimeter, UL-94, and limiting oxygen index tests as response. It is shown that melamine-/ammonium polyphosphate–based formulations do not exhibit as good results as ammonium polyphosphate used alone. High performance is observed for 30 wt% ammonium polyphosphate: 60% reduction of the peak heat release rate, high limiting oxygen index (30 vol% O2), and UL-94 V0 ranking at 1.6 mm (V2 at 0.8 mm).
