Disclosed herein are methods of preparing composites from solid elastomer(s) and wet filler(s), as well as products, including composites, vulcanizates, and articles therefrom. The wet filler can have a liquid content of at least 15%. A resulting composite comprises the filler dispersed in the elastomer at a loading of at least 20 phr with a filler yield loss of no more than 10%, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.

Sugar-based mono and diesters are prepared by esterification of 2,5-furan-dicarboxylic acid (FDCA) with an alcohol in the presence of low loadings of a homogeneous organotin (IV) catalyst.

The invention provides a apparatus for reworking of non-vulcanised rubber or de-vulcanized rubber from a rubber component, preferably a rubber tire, to produce recycled rubber. The apparatus comprises a gear pump configured to receive and filter the rubber to produce filtered rubber and a mixer-extruder configured to homogenize and extrude the filtered rubber to produce recycled rubber.

The present disclosure provides a method of processing shell material. Shell material processed in accordance with the methods disclosed herein may be biodegradable and may further represent a new type of useful material. By way of example, the processed shell material may be useable as a material to make useful materials, items, objects and/or tools.

Included is a method of preparing a compound for bonded magnets, the method including: coating a magnetic material having an average particle size of 10 μm or less with a thermosetting resin and a curing agent at a ratio of the equivalent weight of the curing agent to the equivalent weight of the thermosetting resin of 2 or higher and 10 or lower to obtain a coated material; granulating the coated material by compression to obtain a granulated product; milling the granulated product to obtain a milled product; and surface treating the milled product with a silane coupling agent to obtain a compound for bonded magnets, the method either including, between the granulation and the milling, heat curing the granulated product to obtain a cured product, or including, between the milling and the surface treatment, heat curing the milled product to obtain a cured product.

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.

The fluid feeding system includes a feed channel connected to the discharging device, a pump connected to the feed channel, a valve for blocking a flow of the fluid that flows toward the introduction chamber via the feed channel, and a control device for determining a pressure state on the pump side and carrying out an opening-and-closing control of the valve 70 based on the determination result. The control device carries out the opening-and-closing control in which the valve is made into an open state when the control device determines that a pressure P1 on the pump side reaches a pressure state exceeding a given pressure.

A method of melt blending a polypropylene and the melt blended polypropylene therefrom, comprising providing a base-polypropylene having a MFR of less than 15 g/10 min and a molecular weight distribution (Mw/Mn) within the range from 5 to 16, and comprising hindered phenol and phosphorous-type antioxidants, and within the range from 5 ppm to 4000 ppm of an alkyl radical scavenger relative to the total weight of the components to form a melt blended polypropylene; melt blending the melt blended polypropylene at a temperature of at least 210° C.; and isolating a melt blended, melt blended polypropylene.

A tire tread and a tire are provided, more particularly, a tire having a tread or other elastomeric component within enhanced composite material properties, including, but not limited to, modulus ratio, percent elongation at break, and/or tan delta, wherein the tire, tread or other elastomeric component comprise composites characterized by well dispersed reinforcing filler, which can be indicated by macrodispersion.

The present disclosure relates to a preparation method of a super absorbent polymer. More specifically, it relates to a preparation method of a super absorbent polymer capable of significantly reducing the amount of fine powder generated during the process by mixing a hydrogel polymer with an additive having a specific structure, pulverizing it, and then drying it with a paddle-type dryer.
