The present invention provides a flame-retardant polyolefin resin composition having superior molding processability, a resistance to thermal deformation and suitable stretchability and intensity, which is rich in elastic deformation. The present invention provides a flame-retardant polyolefin resin composition comprising component A (a thermoplastic resin having a carbonyl oxygen atom in the molecular skeleton), component B (a polymer alloy containing an ethylene component and a propylene component), component C: a modified polyolefin polymer containing an acidic functional group and having a weight average molecular weight of 10,000-80,000 and component D (an inorganic metal compound), and substantially free of a halogen atom.

Flame-retardant polyolefin resin composition and adhesive tape substrate composed of the composition, and adhesive tape

An aqueous dispersion type pressure-sensitive adhesive composition contains an acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type and at least one hydrophilic polymer selected from the group consisting of polyalkylene glycols, polyvinylpyrrolidone, poly(vinyl alcohol)s, and poly((meth)acrylic acid), the amount of the hydrophilic polymer being from 0.5 to 15 parts by weight per 100 parts by weight, on a solid basis, of the acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type, and a pressure-sensitive adhesive product has a pressure-sensitive adhesive layer formed from the aqueous dispersion type pressure-sensitive adhesive composition.

Aqueous dispersion type pressure-sensitive adhesive composition and pressure-sensitive adhesive product

An aqueous pressure-sensitive adhesive composition of the invention comprises a rubber-based latex and a tackifier resin emulsion, wherein the tackifier resin emulsion is that obtained by emulsifying a tackifier resin in the presence of an emulsifier containing an ammonium salt of rosins; and the aqueous pressure-sensitive adhesive composition contains a water-soluble salt of casein as protective colloid. The aqueous pressure-sensitive adhesive composition is excellent in mechanical stability and insulating characteristics and has good moisture-proof adhesive strength.

Aqueous pressure-sensitive adhesive composition, pressure-sensitive adhesive tape and wire harness

An aqueous dispersion type pressure-sensitive adhesive composition contains a polyalkylene glycol having a weight-average molecular weight of from 20,000 to 5,000,000 or at least one hydrophilic polymer selected from the group consisting of polyvinylpyrrolidone, poly(vinyl alcohol)s, and poly((meth)acrylic acid) in an amount of from 0.5 to 15 parts by weight per 100 parts by weight, on a solid basis, of the acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type; and a pressure-sensitive adhesive product contains a pressure-sensitive adhesive layer formed from the aqueous dispersion type pressure-sensitive adhesive composition.
