PC(polycarbonate)/PBT(polybutyleneterephthalate) mixture is usually used for housing-reflector material of automotive fog lamp. This material has high HDT(Head Deflection Temperature) and is capable of being aluminum metalized for high reflectivity. However, PC/PBT mixture is more expensive than PP(polypropylene) which is used for automotive head lamp housing. Although PP is cheaper than PC/PBT mixture, PP is not used for light reflector because of its non-polarity. Polarity of material is essential to be aluminum metalized. In this study, PET based new material for housing-reflector material of fog lamp housing, which has polarity and high HDT, is developed to reduce its cost as well as improve its quality..
