Abstract:
A composition includes specific amounts of a poly(butylene terephthalate), a reinforcing filler, and a polycarbonate that includes a copolyestercarbonate and a polycarbonate-polydiorganosiloxane block copolymer. The copolyestercarbonate includes aliphatic ester groups. The composition, which exhibits a desirable balance of melt flow and ductility, is especially useful for forming thin plastic parts of consumer electronic devices, including mobile phones.
Abstract:
Glass filler-reinforced solid resins and methods of making the same. The method includes contacting a flowable resin composition and a tool. The flowable resin composition includes a flowable resin and glass filler. The method includes molding or forming the flowable resin composition with the tool. The method includes curing the flowable resin composition, to form the glass filler-reinforced solid resin. Substantially all the surface of the tool that contacts the flowable resin composition during the curing thereof has a surface roughness Ra of about 2 microns or less. A refractive index of the glass filler is within about 0.100 of a refractive index of a cured product of the flowable resin in the glass filler-reinforced solid resin.
