Polyphenylene sulfide-based heat-shrinkable tube and component covered with the tube
The present invention provides a heat-shrinkable polyphenylene sulfide-based tube containing a resin composition (A) including a thermoplastic polyphenylene sulfide-based resin (a) as a main constituent, having a difference of 35° C. or more between the cold crystallization temperature Tc as measured by a differential scanning calorimetry in accordance with JIS-K7121 and the glass transition temperature Tg measured in the same manner, and having the glass transition temperature Tg between 65° C. and 85° C.; and the invention provides a component covered with the tube. The heat-shrinkable polyphenylene sulfide-based tube fulfills the characteristics required for a heat-shrinkable tube, such as heat resistance, low-temperature shrinkage characteristics, electrical characteristics, chemical resistance, and electrolytic solution resistance.
