According to at least one embodiment, the rotational speed of the first roller is higher than the rotational speed of the second roller. According to at least one embodiment, the thermoplastic resin composition contains (A) 100 parts by mass of a thermoplastic resin, (B) 1-60 parts by mass of carbon nanotubes and (C) 1-100 parts by mass of at least one type of material selected from the group consisting of acetylene black and graphite.

Toothed belt

A toothed belt is provided with toothed portions arranged at a regular pitch in a belt length direction. A belt body is made of a rubber composition containing, as a main ingredient of a rubber component, ethylene--olefin elastomer having an ethylene content of 44% by mass to 66% by mass. A reinforcing fabric is adhered to a surface of the belt body on a toothed side, with a reinforcing fabric adhesion coat interposed between the reinforcing fabric and the belt body. The reinforcing fabric adhesion coat is made of a rubber composition containing hydrogenated nitrile-butadiene rubber as a main ingredient of a rubber component.

10752784 · 2020-08-25 · ·

With the binder produced according to the invention, a number of coating products can be produced which adhere to plastics directly and without any chemical or physical pretreatment. Base coats, high-gloss lacquers, metallic lacquers, clear lacquers and effect lacquers can be produced which can be applied directly on plastics; this is an absolute novelty because pretreatment is no longer required. With the binder according to the invention it is also possible to formulate adhesives which guarantee very good bonding between plastics themselves and also paperboard packaging. The invention relates to the binder as well as base coats based on them, one-coat lacquers and adhesives.

Cationomeric Polyolefin Compositions and Methods for Production and Use Thereof
20200172691 · 2020-06-04 ·

Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.
