The invention relates to a composition of bitumen bases comprising at least: a. 70 to 99 wt.% of at least one bitumen base having a penetrability at 25 °C less than or equal to 220 10 -1 mm and a softening point greater than or equal to 35 °C; b. 1 to 30 wt.% of at least one slurry residue from a slurry-phase hydroconversion process, said slurry residue having a penetrability at 25 °C less than or equal to 50. 10 -1 mm and a softening point greater than or equal to 50 °C. The present invention thus enables recycling of an ultimate slurry residue under vacuum for use in the manufacture of road bitumen.
摘要:
[Object] To provide: an acrylic rubber composition, which is improved in roll tackiness upon processing and in dough-like-material tackiness between dough-like materials themselves, and which is remarkably improved in processing characteristic, without deteriorating resultant normal physical properties; and an acrylic rubber composition molded and used for a sealing part such as an O-ring, gasket, and packing. [Solving means] An acrylic rubber composition comprising 100 parts by weight of an ACM polymer, which contains monomers each having a carboxyl group(s) as crosslinking-site monomers, respectively, and 5 to 30 parts by weight of vein graphite or flake graphite; and an acrylic rubber composition comprising 100 parts by weight of an ACM polymer, which contains monomers each having a carboxyl group(s) as crosslinking-site monomers, respectively, 5 to 30 parts by weight of vein graphite or flake graphite, and 0.5 to 1.5 parts by weight of a liquid paraffin.

An object of the invention is to provide resin premix compositions which include a polyol and a hydrocarbon foaming agent while still exhibiting good storage stability, the polyol being obtained without the use of ring-opening polymerization reaction of a cyclic ether. The resin premix composition of the invention includes at least a polyol and a hydrocarbon foaming agent, the polyol including a polyether ester polyol (A) obtained by reacting a polyether polyol with a fatty acid and/or a fatty acid ester, the polyether polyol being obtained by condensing a polyhydric alcohol including 50 mol% or more of a trihydric or higher alcohol.

The invention provides hot melt adhesive with wide service temperature ranges, methods of using the adhesive to bond substrates together, to close/seal cases and cartons and the like, and to articles of manufacture comprising the adhesive. The hot melt adhesive comprises a metallocene catalyzed polyethylene copolymer, less than 10 wt % of a functionalized metallocene catalyzed polyethylene copolymer, greater than 22 wt % of a wax, a tackifier and optionally, additives.
