The thermal properties of aluminium hydroxide as filler in recycled PP composite

Abstract

This study is about the composite of recycled polypropylene (RPP) composites filled with aluminium hydroxide (Al(OH)3) . Maleic anhydride-grafted polypropylene (MAPP) was also used as compatibilizer between filler and matrix to improved the bonding between recycled polypropylene (RPP) matrix and aluminium hydroxide (Al(OH)3). The RPP composite were compounded using z blade mixer with rotor speed 50 rpm. The characterization of RPP was done by Fourier Transform Infrared (FTIR). Thermogravimetry analysis (TGA) were conducted to study the thermal properties of PP composite. TGA curve exhibited a significant improvement in thermal properties behavior of RPP composite under the effect of different aluminium hydroxide (Al(OH)3 filler loading (0, 20, 30, 40 wt %) with and without maleic anhydride-grafted polypropylene (MAPP) coupling agent. For DSC analysis, the results show that the melting temperature (Tm) the increasing filler loading.
