• Polybutylene terephthalate (PBT) has such good characteristics as high strength, wear and chemical resistance, etc. Recently, flame retardant PBT has been developed for electric appliances, but it shows more change in color than not-flame retardant PBT after UV light exposure. In this report, the dependence of the color change of flame retardant PBT on the content of titanium oxide and oxygen index, which is the measure of flame retardant degree, was determined. Furthermore, the effect of UV absorber on the color change was examined. By the addition of 1% titanium oxide and 0.5% UV absorber, the color difference of flame retardant PBT was reduced to about one-third of its initial value. The color difference was approximately the same for those having the oxygen index more than 25.
