Heat-shrinkable tube

Abstract

Abstract PURPOSE:To enable to obtain an article which is superior in low smoke, fire retardant and heat resistance, by irradiating an FEP resin composite which has used a polyfunctional monomer such as triallyl cyanurate or triallyl isocyanurate as additives with electron rays. CONSTITUTION:Electron rays are irradiated to a resin composite consisting of tertrafluoroethylene-hexafluoropropylene copolymer to be obtained by loading one or more kinds of polyfunctional monomers selected out of a group consisting of triallyl cyanurate, triallyl isocyanurate, triacryl cyanurate and meta-acryl cyanurate and meta-acryl cyanurate and crosslinked. As for a load of the triallyl cyanurate or triallyl isocyanurate, 0.1-20wt. is desirable. In addition to the above, as for an absorbed dose in an FEP resin composite, more than 3M rad and less than 25M rad is desirable with this construction, in addition to low smoke and fire retardant, heat resistance is improved.
