Hollow extrusion molded product, its crosslinked product, heat shrinkable tube and multi-layer heat shrinkable tube

摘要

It has flame retardancy that passes the VW-1 combustion test, has excellent mechanical strength, does not have odor problems such as acetic acid odor, and does not generate die residue during extrusion molding, and the tube appearance is good. A hollow extruded body, a crosslinked body thereof, a heat-shrinkable tube obtained from the crosslinked body, and a multilayer heat-shrinkable tube are provided. A resin composition containing an ethyl ethylene acrylate copolymer or an ethyl ethylene acrylate copolymer and a linear low-density polyethylene as a base resin and containing a brominated flame retardant, antimony trioxide and magnesium hydroxide is drawn and molded. The composition ratio of the ethyl ethylene acrylate copolymer and the linear low-density polyethylene, the content of the brominated flame retardant, the content of the antimony trioxide, and the content of the magnesium hydroxide are specified. A hollow extruded body within the range, a crosslinked body thereof, a heat shrinkable tube obtained from the crosslinked body, and a multilayer heat shrinkable tube.
