    摘要: A flame retardant thermoplastic composition having excellent physical properties comprises about 20 to about 90 wt. % of a polycarbonate resin; up to about 35 wt. % of an impact modifier; about 0.5 to about 30 wt. % of a polysiloxane-polycarbonate copolymer comprising about 8 to about 30 wt. % polydimethylsiloxane units or the equivalent molar amount of other diorganosiloxane units; and about 0.5 to about 20 wt. % of a phosphorus-containing flame retardant, each based on the total combined weight of the thermoplastic composition, exclusive of any filler. In one embodiment a sample of the thermoplastic composition having a thickness of 2.5 mm (±10 % ) achieves a UL94 5VA rating Thinner samples may also achieve this rating. The compositions are useful in forming flame retardant thin-walled articles.

    摘要: A flame retardant thermoplastic composition having excellent physical properties that includes 20 to 90 wt. % of a polycarbonate resin; from 1 to 35 wt. % of an impact modifier; from 0.5 to 30 wt. % of a polysiloxane-polycarbonate copolymer including from 8 to 30 wt. % polydimethylsiloxane units or the equivalent molar amount of other diorganosiloxane units; from 0.5 to 20 wt. % of a phosphorus-containing flame retardant, and from 3 to 30 wt. % of metal fiber, each based on the total combined weight of the thermoplastic composition, exclusive of any filler. In one embodiment, a molded sample of the thermoplastic composition having a thickness of 3.0 mm (±10%) has an EMI shielding of at least 20 dB. In addition, a molded sample of the thermoplastic composition is capable of achieving UL94 V0 or V1 rating at a thickness of 1.5 mm (±10%). The compositions are useful in forming flame retardant articles having EMI shielding characteristics.

    摘要: A composition containing a bulk polycarbonate-containing resin component; a polycarbonate-siloxane copolymer in an amount sufficient to provide an amount of siloxane of at least 3% by weight of the total composition; and a colorant composition comprising titanium dioxide having an organic coating, for example a coating comprising a polysiloxane, in which the amount of titanium dioxide is from 1 to 2.5 %, preferably 1 to 2.0% and more preferably 1 to 1.5% by weight of the total composition has both light color and good flame-retardance. The composition can be used to prepare shaped article s, particularly those with thin wall region that achieve a V0 UL fire rating at the first thickness.
