Predictive Tools to Assist the Development of Flame Retarded Phosphorus‐Free Polypropylene and Identify Synergy between Flame Retardants
نویسندگان
چکیده
The development of flame-retarded polypropylene is carried out with the ultimate goal obtaining a UL94-V0 not only halogen- but also phosphorus-free formulation because phosphate rocks, precursors phosphorus-based flame retardants, are recognized as critical raw materials within Europe. Different retardants (FRs) (melamine, ester, and radical generator) used. A statistical approach applied to predict UL94 behavior develop optimized formulations in terms cost, filler or phosphorus content. Models for most common “nondripping” well “nonflaming dripping” proposed. experimental validation has shown reliability models proposed their usefulness assist speed up formulations. use gives insight into interactions between thus suggesting if potential synergies take place, before studying FRs system details. Indeed, melamine ester generator discovered. Thanks these that V0 rating can be achieved. formulation, comprising generator, identified optimal reduced

متن کاملOrganophosphorus Flame Retardants (OPFR): Neurotoxicity
Organophosphorus flame retardants (OPFRs) are used as additives in plasticizers, foams, hydraulic fluids, anti-foam agents, and coatings for electronic components/devices to inhibit flames. These chemicals were developed and used as flame retardants because of environmental and health concerns of previously used brominated and chlorinated flame retardants (FRs). OPCFRs are divided into five mai...
