A series of samples based on poly(3-hydroxybutyrate) (PHB) containing five different additives were prepared and their thermal stability flammability discussed. The first underwent screening by using Pyrolysis Combustion Flow Calorimeter (PCFC) analyses. Then, four selected for further investigations. PHB composites sepiolite (Sep.) inorganic nanofiller, also organic ammonium polyphosphate (APP) examined behavior PCFC, thermogravimetric analysis (TGA), flame test, Differential Scanning...
Abstract Ammonium polyphosphate (APP)‐based additives and Al 2 O 3 TiO nanoparticles have been incorporated separately or combined at a 15 wt% global percentage in poly(methyl methacrylate) (PMMA). APP–based additive containing melamine phosphate has led to an intumescent behavior during cone calorimeter tests, whereas thermal stability was particularly improved by the use of oxide nanoparticles. APP with combination allowed significant synergism on flame retardance be achieved, owing...
This work visualizes the complementary actions of organic and mineral additives in model thermoplastic polymer composites terms Flame Retardancy Index ( FRI ). Thermal flame retardancy behaviors ethylene‐vinyl acetate copolymer (EVA) containing calcium carbonate (CC) ammonium polyphosphate (APP) were studied varying composition 80/20 EVA/( x CC + (20 − )APP) with denoting 0, 5, 10, 15, 20 wt%. Thermogravimetric analysis (TGA) revealed that onset temperature remaining residue increased by...
Abstract Nanometric aluminum oxide particles were modified by phosphonic acid‐based oligomers of aromatic polyester, polyether, or polydimethylsiloxane (PDMS). The grafting process was characterized FTIR spectroscopy and thermogravimetric analysis (TGA) showing that covalent bonds must have formed between the oligomers. highest yield achieved in dichloromethane (CH 2 Cl ) solvent. Then, nanocomposites prepared melt‐blending a poly(methyl methacrylate) (PMMA) matrix. best results terms...
This work aims to investigate the fire retardant properties of a novel type high‐density polyethylene composites. Our intumescent system consists in using classical flame retardants such as ammonium polyphosphate, pentaerythritol combination with porous mesostructured silica (SBA‐15) fillers. Prior use, SBA‐15 was chemically modified different organic and inorganic grafts order obtain some specific properties, an improved compatibility polymer, or types surface acidity increase charring...
Abstract Grafting of ethylene glycol methacrylate phosphate (EGMP) monomer polymerized from alumina nanoparticles has been performed in order to confer a better thermal stability and fire retardancy PMMA PS nanocomposites. polymerization processes have investigated using FTIR, TGA, elemental analyses. Thermal decomposition routes polymer grafted studied thermogravimetric analysis compared with the behavior same modified octylsilane. The EGMP supported by is higher than that free EGMP....
