The effects of coupling agent on the flame retardant properties of PP/ATH nanocomposites

| Summary: | It is known that polymeric materials are easily to get on fire due to their chemical
structures. Thus the flame retardant material such as aluminium hydroxide (ATH) is used to
improve the flame retardancy property of polymers. Polypropylene (PP) with various amount of
nano-sized ATH particles of (5, 10, 20, 30, 40 wt%) were compounded with an extruder machine.
The effects of two different type of coupling agent (3-Aminopropyltriethoxysilane (APS) and
Maleic anhydride grafted polypropylene (MAPP)) on the flame retardant properties were compared.
All samples were characterized with two flame tests; the limiting oxygen index (LOI) and UL94
horizontal burning test (UL94 HB). It is found that both tests showed improvement on the flame
resistance properties of the nanocomposites, mainly at high ATH loadings. Type of coupling agents
affects the flame retardancy properties of PP/ATH nanocomposites. |
