Abstract

PURPOSE:To improve the thermal coloration and heat deterioration preventing effect by multiplication effect of a stabilizer-plasticizer-antioxidant. CONSTITUTION:Peripheries of a glass tube 1 near filaments 2 provided on both ends of a fluorescent lamp is covered with heat-shrinkable tubes or film sheets 3 of excellent thermal resistance, and outer peripheral surfaces of the films 3 and an uncovered peripheral surface of the glass tube 1 are covered with a heat-shrinkable tube 4 made of vinyl chloride resin. The film 3 contains 40-60 parts by weight of trimellitic acid ester plasticizer, 1-7 parts by weight of bisphenolic antioxidant and 2-6 parts by weight of maleate polymer and mercapto tin stabilizer.
