| Abstract Scope |
Polypropylene (PP) is a commodity plastic utilized in various applications ranging from automobiles, construction, packaging and textiles. However, PP is highly combustible and burns by releasing smoke and toxic fumes which limits its usage. In the present study, flame retardant additives- SiC (~10 wt%),CNT (~5 wt%) and graphene nanoplatelets (~5wt%) are incorporated in the PP matrix to enhance its thermal damage tolerance.The synergistic effect of SiC, CNT and GNP in PP matrix exhibited maximum thermal stability observed during DSC and TGA analysis with ~17% increment in degradation temperature and residue% by 19%.The vertical and horizontal burn test showed ~15-20% reduction in burn rate accompanied with reduction in flame dripping for SiC, CNT and GNP reinforced PP matrix. Such flame retardation and thermal damage tolerance in these composites makes SiC, CNT and GNP ideal additives to enhance the thermal stability of PP for potential application in defense and fire protection sectors. |
