A halogen-free pressure-sensitive adhesive tape including a tape substrate made of a non-halogen resin composition containing no halogen elements and, applied to at least one side of the substrate, a pressure-sensitive adhesive containing a modified acrylic resin obtained by copolymerizing acrylic acid or an acrylic ester with a monomer which forms a tackifier resin.

Halogen-free pressure-sensitive adhesive tape

A polypropylene-based resin composition including (A) 70 to 96 mass % of a polypropylene-based soft resin having an ISO D hardness of 35 or less and containing 25 to 55 mass % of xylene-insoluble part at room temperature and 75 to 45 mass % of xylene-soluble part at room temperature, (B) 2 to 10 mass % of homopolypropylene having a melt mass flow rate (MFR) at 230&#xb0; C. under a load of 2.16 kg measured in accordance with JIS K 7210 of 1 to 30 g/10 min. and stereoregularity (meso pentad fraction) of 90% or more, (C) 2 to 20 mass % of a propylene-ethylene random copolymer having an ethylene content of 1 to 10 mass %, and (D) 0 to 15 mass % of a platy inorganic filler.

Polypropylene-based resin composition and molded product thereof

A corrugated tube having an elastic material in which a slit is formed over the entire length of a cylindrical periphery of a flexible tube main body, and a wire harness is contained with the slit being in a closed state. Both ends of the slit are formed over a predetermined peripheral width with a soft material composition having a lubricant and a soft material having a hardness less than that of an outer skin of electric wires that constitute a wire harness to be contained. The corrugated tube is capable of accommodating a wire harness with no injury and enabling a smooth wire harness accommodating operation.

Corrugated tube

A wire-protective tube which has a resin composition having 100 parts by weight of a polypropylene, from 10 to 500 parts by weight of a propylene block copolymer having a propylene monomer unit and an ethylene monomer unit in a specific proportion, from 1 to 50 parts by weight of a bromine-based flame retardant, and from 1 to 30 parts by weight of a flame retardant aid.
