Antidripping and Fire resistancy of Intumescent Flame Retardant in combination with MWCNT in poly(butylene succinate) composites

Poly (butylene succinate) (PBS) is such a commercially available biodegradable aliphatic polyesters and has already been used as films for packaging, sheets, bottles, and injectionmoldedproducts1. For environmental concerns, intumescent flame retardant (IFR) is considered as a promising halogen-freeflame retardant additive due to it’s advantages of low smoke, low toxicity, low corrosion, and no molten dripping during afire2, also multi wall carbon nanotube (MWCNT) has synergic effect on flame retardancy and thermal degradation of polymer composites3. In the current work, the intumescent flameretardant system has been blended with PBS to obtain flame retardant and environmental friendly composites and alsoMWCNT has been used as a synergistic agent. The flame retardancy and thermal properties of the composites were evaluated by limiting oxygen index (LOI), UL-94, microscalecombustion calorimetery, and thermogravimetric analysis. The thermal degradation process has been investigated by RTFTIR
