Phoslite™ B407A

• Phoslite B407A additive flame retardant is a very effective solution for flameproofing Polyolefins (PP homopolymer, co-polymer, HDPE and LLDPE).
• Dosage for UL-94 V2 rating range from 4,5% to 10%, depending on polymer type and formulation (around 4,5 % on PP homo, 6% in PP copo, 8% on LLDPE and 8% on HDPE).
• Phoslite B407A is endued with a very high thermal stability and it is very easy to disperse in a polymer matrix.
• Phoslite B407A does not affect substantially mechanical properties of the host polymer at concentrations practically in use.
• Phoslite B407A can be used in mineral filled PP formulations, like Talc, Barium Sulfate and Calcium Carbonate compounds, showing UL 94 V2 behaviour with low extinguishing times.
• Phoslite B407A allows to obtain GWFI at 960°C (both at 3 and 1 mm in PP homo and co-polymer) and high GWIT in the range 750°C – 900°C depending on final item thickness.
• Thanks to its very fine particle size, Phoslite B407A can be successfully used for flame-retarding PP films, moulded in blow or cast extruded.
• The additive leaves full freedom of colorability to the compounder and the moulder.
• Phoslite B407A does not increase equipment’s corrosion, even without any extra addition of anti-acids and show an outstanding thermal and process stability.
• Phoslite B407A as such has very high UV stability.
• Phoslite B407A fully comply with the requirements of the RoHS and WEEE directives.

¹Typical properties; not to be constructed as specifications

• Phoslite B407A is endued with high thermal stability, therefore it is in position to overcome both extrusion and injection moulding normal processing conditions.
• Phoslite B407A does not interact with the common processing additives like: stabilisers, crosslinking agents, processing aids, inorganic fillers, pigments, etc.
