Flame retardancy of the composites were characterized by thermalgravity analysis, limited oxygen index, and UL94 plastic combustion testing, whiletheir mechanicalproperties were studied by impact testing. The resultsshowed that thePA6/OMMT composites with addition ofredphosphoruscan passthe UL94 testandex-hibit thebest property combinationswhen the massfraction ofOMMT isbetween5%7%.Keywords: montmorillonite; Nylon6; combustion propertyl:2007-11-26Te:!(1982 ),o,V3. *Y.M,/rTBr?1-2bFrE?v4,wLnm1am2bm1 FsMMTOMMTTGwLFig.1 TG curves of materials withdifferentamounts of MMT and OMMTVm1A,Fs3%, 5%,10%,20%MMT3%, 5%OMMTHsSBPA6Mv,(340 350 ebOMMTc10%H,s320 e ,F20%OMMTs280 eb0rW,b2.2 ?2.2. 1 KV11(LOI)bV1 1LOITable 1 LOI resultsof composite materials of different compositesLOICBPA6 20.4PA6/MMT3 19.2PA6/MMT5 19.5PA6/MMT10 19.3PA6/MMT20 19.1PA6/OMMT3 19.1PA6/OMMT5 18.5PA6/OMMT10 18.2PA6/OMMT20 17.9PA6/P 21.2PA6/OMMT5/P 19.1PA6/MMT5/P 19.3VV1s,BPA6LOI20.4,FNa-MMTLOIhl,(CbFOMMTV(C,F9FLOI/bBPA6F,4LOI,CbPA6FOMMTlBPA6v&,V7|4bFOMMTVC,H,$+,f+,.A(&Y-d)/r,J., 2005,28(2);90-93.3 f+,1.E/M.:,2005:366-422.4 Hmadi S J, Huang Y D, LiW.
