Abstract
The present disclosure relates to a heat-shrinkable tube having tearability, which is made of a fluororesin, and particularly, to a heat-shrinkable tube having excellent tear straightness. Further, the present disclosure relates to a tube having high heat-shrinkage rate at low temperature. A tube including at least a fluororesin as a base resin, in which the thickness of the entanglement unit of a polymer observed on a cross-section in a longitudinal direction of the tube after being shrunk at 200° C. by 35% or more is 1 μm to 9 μm, has excellent tear straightness.
