Fabrication and characterization of halogen-free flame retardant polyolefin foams with cell sizes in the microcellular range
Mayor advances have been made in the field of halogen-free flame retardant (FR) composites in the last years, mainly due to increasing regulatory pressures. This paper focuses in aluminium trihydroxide (ATH) as the halogen-free flame retardant and low density polyethylene (LDPE) as the polymer matrix of the FR foam. A large number ofliterature analyzes dense materials based on LDPE and ATH. The main goal of this research is to achieve a cellular structure by foaming, when high loading levels (nearly 60 wt%) of ATH are introduced. This is a difficult task due to the high amount of filler in the formulation. The aim is to reduce density without losing thermal and mechanical properties. By means of scanning electronic microscopy (SEM), thermogravimetric analysis (TGA), melt flow index (MFI), air pycnometry, mechanical testing at low strain rates, limiting oxygen index (LOI), and bomb calorimeter a complete study of the foamed samples was made in order to characterized their cellular structure as well as their thermal, mechanical and combustion properties.
