Abstract
(EN)
A flame retardant material is disclosed comprising a polymer and at least two high purity, fine precipitated Al(OH)3 flame retardant fillers, characterised by one having, in isolation, a specific surface area of at least 130% that of another; for example, a first AL(OH)3 filler having, in isolation, a specific surface area of 4 to 8 m2/g (ideally between 6 to 8 m2/g) and a second AL(OH)3 filler having, in isolation, a specific surface area of 8 to 14 m2/g (ideally between 10 to 12 m2/g).
