Polycyclohexylene dimethylene terephthalate based resin composite with excellent heat resistance

摘要

The present invention relates to a polycyclohexylenedimethylene terephthalate resin composition comprising 0.01 to 50 parts by weight of TiO ₂ and 100 parts by weight of the polycyclohexylenedimethylene terephthalate resin per 100 parts by weight of the polycyclohexylenedimethylene terephthalate resin, portion comprises talc and acicular whiskers of one or more materials selected from the group consisting of 0.01 to 100 weight parts with respect to the TiO ₂ are poly-cyclohexylene dimethylene, characterized in that TiO ₂ is coated with aluminum oxide and organosiloxanes To a terephthalate-based composite material composition. INDUSTRIAL APPLICABILITY The polycyclohexylenedimethylene terephthalate composite material composition of the present invention can be injection-molded, has a low water absorption rate, is excellent in heat resistance, excellent in discoloration resistance by heat, excellent in flame retardancy, It can be used for LED (light emitting diode) reflector.
