摘要： An object of the present invention is to provide a heat shrink tube excellent in peelability and transparency, and a method for producing the heat shrink tube. The present invention provides a peelable heat shrink tube comprising a composition containing a melt-processable fluororesin and PTFE, the PTFE lacking a heat history of its melting point or higher after polymerization and having a specific gravity, as measured according to ASTM D4894, of 2.20 or less. The content of the PTFE is 0.05 to 3.0 wt% based on the total weight of the melt-processable fluororesin and the PTFE. The present invention also provides a method for producing the tube which comprises melt-extruding the composition at a temperature lower than the melting point of the PTFE.

摘要： A process for producing a multi-layer heat shrinkable tube having an adhesive layer on an internal surface thereof, which comprises the following steps 1 to 4:
(1) Step 1 of co-extruding a radiation-crosslinking composition comprising a fluorine-containing polymer and a polyfunctional monomer and a fluorine-containing polymer composition comprising 100 parts by weight of a fluorine-containing polymer and 2 to 30 parts by weight of an unsaturated compound containing at least one polar group selected from the group consisting of an epoxy group and a carboxyl group to form a tube-like formed product of a 2-layer structure having an outer layer composed of the radiation-crosslinking composition and an inner layer composed of the fluorine-containing polymer composition;
(2) Step 2 of irradiating the tube-like formed product with ionizing radiation to crosslink the radiation-crosslinking composition of the outer layer and graft-modify the fluorine-containing polymer composition of the inner layer;
(3) Step 3 of expanding the tube-like formed product in a radial direction thereof under heating; and
(4) Step 4 of cooling the tube-like formed product to fix the form expanded in the radial direction.
