    摘要: The present invention provides a polyester heat-shrinkable tube for coating electrolytic condenser molded from a resin composition comprising a) 80 to 99 wt % of a copolymerized polyester resin with an intrinsic viscosity of 0.65 to 1.0 dl/g, which comprises 1 to 15 mol % of polyethylene naphthalate and 85 to 90 mol % of polyethylene terephthalate, and b) 1 to 20 wt % of polybutylene terephthalate resin. The polyester heat-shrinkable tube of the present invention has superior heat resistance, strength and coating-adhesion property, so that no cracks may occur in dry-heat treatment after the coating and contraction step, and also that the tube can be tightly adhered to the condenser.
