POLYCYCLOHEXYLENE DIMETHYLENE TEREPHTHALATE BASED RESIN COMPOSITE WITH EXCELLENT HEAT RESISTANCE

摘要

The present invention relates to a polycyclohexylene dimethylene terephthalate based composite material composition with an excellent heat resistance, comprising: a polycyclohexylene dimethylene terephthalate resin; 0.01 to 50 parts by weight of TiO_2 with respect to 100 parts by weight of the polycyclohexylene dimethylene terephthalate resin; and 0.01 to 100 parts by weight of at least one or more materials selected from between talc and/or needle-shaped whisker with respect to 100 parts by weight of the polycyclohexylene dimethylene terephthalate resin, wherein TiO_2 is coated with aluminum oxide and organosiloxane. According to the present invention, the polycyclohexylene dimethylene terephthalate based composite material composition can be injection molded, and has a low moisture absorption rate, a high heat resistance, an excellent resistance to discoloration due to heat, an excellent flame-resistance and a high whiteness, so as to be also applicable to a reflection plate for a light emitting diode (LED).
