The Processing Properties and Rheology Behavior of Flame Retardant PP with NER/OMMT Nanocomposites and TPP

The processing properties and rheology behavior of flame retardant PP obtained with novolac epoxy/OMMT(NER/OMMT) nanocomposites and triphenyl phosphate(TPP) mixture as flame retardant agent was studied,and the flame retardent PP with different content and ratio of NER/OMMT-TPP was characterized via melt index apparatus and RAD-3 rheometrics.The effect of content and mass ratio of NER/OMMT-TPP on melt index,complex viscosity,G′、G″ and tanδ of flame retardant PP was discussed.
