The present invention addresses the problem of providing an electroconductive resin composition which combines high electrical conductivity with excellent processability. The electroconductive resin composition comprises a thermoplastic resin (A), carbon nanotubes (B) having an outer diameter of 100 nm or smaller, and an aromatic-monomer-modified polyolefin wax (C) obtained by modifying a polyolefin wax with an aromatic monomer. The composition comprises the thermoplastic resin (A), the carbon nanotubes (B), and the aromatic-monomer-modified polyolefin wax (C) in amounts of 74.9-99.4 parts by mass, 0.5-25 parts by mass, and 0.1-10 parts by mass, respectively, with respect to 100 parts by mass of the sum of the thermoplastic resin (A), the carbon nanotubes (B), and the aromatic-monomer-modified polyolefin wax (C).

A foaming resin composition of the present invention contains an aromatic vinyl-based resin and zinc oxide, wherein the size ratio (B/A), in which peak A is a 370 nm to 390 nm region and peak B is a 450 nm to 600 nm region, of zinc oxide is approximately 0.01 to approximately 1 when photoluminescence is measured, and the BET surface area thereof is approximately 1 m.sup.2/g to approximately 10 m.sup.2/g.

An improved method forms and employs a wax to modify asphalt. The method includes: (a) selecting a solid polymeric material, (b) heating the solid polymeric material in an extruder to produce a molten polymeric material, (c) filtering the molten polymeric material, (d) placing the molten polymeric material through a chemical depolymerization process in a reactor to produce a depolymerized polymeric material, and (e) adding the depolymerized material to a pre-wax mixture to produce a polymer-modified asphalt. The addition of wax reduced the mixing time necessary to achieve improved polymer dispersion compared to the control formulation modified bitumen and reduced the viscosity of the neat bitumen. Pre-polymer addition of wax is detrimental to most properties of the resulting modified asphalt. Post-polymer addition improved viscosity reduction, higher softening point and improved dimensional stability.

Mineral wool insulation products are provided. The mineral wool insulation includes a plurality of mineral wool fibers and a wax emulsion applied to the mineral wool fibers. The wax emulsion imparts excellent water resistance and thermal performance properties to the mineral wool insulation.

A cellulosic particle contains 90 parts by mass or more and 99.5 parts by mass or less of cellulose; and 0.5 parts by mass or more and 10 parts by mass or less of a cellulose derivative.

An extrusion process of a manufacturing system for plastic which also serves as a depolymerization reactor through the use of melting point's temperature as activation energy and liquid solvents. The melting point activation energy and liquid solvents are used to generate a certain level of depolymerization at the manufacturing process of any given plastic product. The process includes several variables that are used in determining a final additive that is introduced at the beginning of the extrusion process. The final additive includes a mixture of a liquid solvents, a molecular filler, chemical carriers, and stabilizers.
