Abstract
An antistatic flame retardant composition comprises a polycarbonate resin; an impact modifier comprising polysiloxane; an antistatic agent; and a flame retardant in a an amount greater than or equal to about 9 wt % of the total composition. Owing to its excellent antistatic, impact and flame retardant properties, the composition can be used in electrical and electronic equipment and precision machinery where high fabrication temperatures and high usage temperatures are often encountered.
Claims19
An antistatic composition comprising:
- a polycarbonate resin;
- an impact modifier comprising a polycarbonate-polysiloxane copolymer;
- an antistatic agent;
- and
- a flame retardant comprising phosphorus, wherein the flame retardant is present in an amount greater than or equal to about 9 wt % of the total composition.
An antistatic flame retardant composition comprising, based on the total weight of the composition:
- about 10 to about 90 wt % of a polycarbonate resin;
- about 1 to about 20 wt % of an impact modifier comprising a polycarbonate-polysiloxane copolymer;
- about 0.01 to about 25 wt % of an antistatic agent;
- and
- greater than or equal to about 9 wt % of a flame retardant comprising bisphenol A bis(diphenyl phosphate).
A method of manufacturing an antistatic composition, comprising:
- extruding a polycarbonate resin, an impact modifier comprising a polycarbonate-polysiloxane copolymer, a polymeric antistatic agent, and a flame retardant comprising phosphorus, wherein the flame retardant is present in an amount greater than or equal to about 9 wt % of the total composition.
