Abstract

Aluminum trihydrate (ATH) of different sizes is added to polypropylene (PP) to prepare a composite which will have both good fire-retardant and mechanical properties. PP/ATH (nano or micro) composites are more fire-resistant and having appreciable mechanical properties as compared to virgin PP. Addition of maleic anhydride-functionalized polypropylene (MAPP) to the composite to increase the compatibility between PP and ATH (nano or micro). The need for developing the mechanical properties of flame-retardant composites is discussed in this paper. The influence of concentration of ATH (nano or micro) in PP/ATH (nano or micro)/MAPP composites is presented. The mechanical, thermal, morphological and flame-retardant properties were studied and discussed. The tensile modulus, hardness and flame-retardant properties increase, while elongation at break and tensile strength decreases with the increase in ATH (nano or micro) content.
