Abstract: A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocayante in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.

Abstract: An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

Abstract: Embodiments of the present disclosure include flexible impregnated articles, composites produced by curing such flexible impregnated article, and processes for forming flexible impregnated articles. The flexible impregnated articles, composites, and processes can be used as alternatives to articles, composites, and processes in a cured-in-place pipe rehabilitation process that include epoxy resins, thus eliminating toxicity issues associated with the use of epoxy resins. The instantly-disclosed flexible impregnated articles, composites, and processes can be particularly useful for the CIPP process in potable water pipe and pressure pipe applications.
