    Abstract: A method for blending functionalized silica with styrene butadiene rubber or ethylene propylene diene monomer rubber can include silica and an organosilane chemically and covalently bound to a surface of the silica. The organosilane can be derived from an organic silane with a functional group. A silica rubber masterbatch for complexing with an emulsion styrene butadiene rubber latex, a synthetic polymer, a natural polymer, or combinations thereof can include the functionalized silica with the organosilane or a blend of organosilanes chemically and covalently bound to a surface of the silica. Each organosilane can have an average tetrameric structure having a T3/T2 ratio of 0.3 to 0.9 or greater as measured by 29Si silicon cross polarization magic angle spinning nuclear magnetic resonance.

    Abstract: A method for dispersing a filler having high agglomerating properties in a resin and a micro-dispersing mixer used in the method are provided. Further, a method for producing a sealing material that can avoid a defect caused by agglomerates of a filler (for example, carbon black) in an electronic material such as a semiconductor package, a masterbatch resin produced by the method, and a micro-dispersing mixer used in the method are provided. When a filler is dispersed in a molten resin composition to produce a filler-dispersed molten resin composition, a resin composition containing filler aggregates and a molten resin composition is preliminarily mixed by a mixing means, and, thereafter, the preliminarily mixed mixture is allowed to pass through the micro-dispersing mixer with a fine flow path to disperse the filler in a filler resin composition.

    Abstract: A thermoplastic material, and in particular a jacket for an electrical cable, and more particularly a jacket for a THHN electrical cable, includes a polyamide base material, a silicon elastomer and an ethylene polymer modified with an unsaturated aliphatic diacid anhydride. The silicon elastomer does not migrate through the jacket. The jacket has a lower coefficient of friction than a cable with a jacket that does not have a silicon elastomer incorporated therein, and the resulting cable requires less force to install than a cable without a lubricant incorporated therein. The cable also has improved flame resistance and elongation-to-break properties. Methods for making these thermoplastic materials are also described.

In the composition of graphene oxide/rubber, the graphene oxide leads to low gas permeability and remarkably reinforces the rubber composition. The epoxy natural rubber or thermoplastic resin is dispersed in the composition of graphene oxide/rubber and forms an islands-in-the-sea structure. The composition has low gas permeability, excellent mechanical properties, and flexibility, and is adhesive to adjacent rubber.

  • Publication number: 20140309320
    Abstract: One or more fly ash materials or other optimized mineral fillers having a particle size distribution that may include cinders of selected sizes is mixed to form a filler. The filler is then mixed with an acid scavenger, an antioxidant, a compatibilizer and an impact modifier into a resin to form either a final composition or a masterbatch. A blowing agent may be added to both. Either the masterbatch or the final composition is mixed with a blend of a mineral oil and a styrenic block copolymer. Thereafter the masterbatch if prepared is mixed into or with a base resin to form the final composition. Fractional melt may be used in the masterbatch and in the final composition. The physical properties of the resulting products can be controlled by varying the ingredients. Some masterbatches are combined to produce products that have improved impact strength and/or that have enhanced toughness when compared to products made using naked or virgin resins.
