Flame retardants for thermoforming applications
Polypropylene and its copolymers, the largest group of resins worldwide, are found in most market sectors: packaging, textile, building, automotive, commodities, electrical appliances and office equipment. Some of these applications require fire retardancy. Lower levels of fire retardancy are usually obtained by addition of flame retardants, based wholly or partly on aliphatic bromine which are efficient but often do not prevent dripping. It is in general more difficult to reach higher level of fire retardancy requiring non-dripping without adding large amounts of flame retardants. These flame retardant systems based often on aromatic bromine are not cost efficient. This paper will review some of the existing range of brominated flame retardants offered for applications in polypropylene, ABS and it will discuss the properties achievable in various types of polymeric systems such as homo- and copolymers with and without reinforcement. New developments to improve cost efficiency will also be reviewed and they will include combination of surface treated magnesium hydroxide with brominated flame retardants.
