Provided is a heat-dissipating elastic body composition. The heat-dissipating elastic body composition according to an exemplary embodiment of the present invention includes an elastic matrix-forming component including a base resin and a vulcanizing agent, and a heat-dissipating filler. Accordingly, the heat-dissipating elastic body may protect a heating element from a physical stimulus such as a vibration or impact transmitted from the outside to a heat dissipater, and rapidly transduce and radiate heat generated in the heating element. In addition, the heat-dissipating elastic body may minimize vibrations caused by a physical stimulus applied from the outside and a noise thereby by minimizing a gap between a heating element and an exterior material, a heat dissipating element or the like, which is adjacent thereto/in close contact therewith. Further, the heat-dissipating elastic body heating element may minimize deterioration by heat generated by a heating element or an external chemical stimulus and may be easily implemented in various shapes, and therefore, it may be widely applied to all industries requiring heat dissipation.

Recycled elements and/or renewable resources, such as recycled carbon black or recycled carbon black and recycled particulate rubber, are incorporated into a rubber composition. The rubber composition can be used to manufacture tires or various tire components including tire subtreads.

Conveyor belts having a reinforcement layer, a carry cover layer above the reinforcement layer, and a pulley cover layer disposed beneath the reinforcement layer, where the carry cover layer includes least one hydrogenated nitrile butadiene rubber (HNBR) material. The HNBR material(s) may have a percentage of hydrogenation of from about 90% to about 96%, from about 92% to about 95%, or even about 94%. The carry cover layer may be from about 4 mm to about 6 mm thick, or even from about 4 mm to about 5 mm thick. In some cases, the reinforcement layer includes a rubber matrix, which may be formed of a nitrile rubber (NBR), or mixture of nitrile NBR and natural rubber blended in a NBR:NR weight ratio of from 3:1 to 9:1. In some aspects, the reinforcement layer includes a plurality of reinforcement plies embedded in the rubber matrix.

A display unit that includes an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the display part and the protective part. The cured resin layer can have a transmittance of 90% or higher in the visible range and a storage modulus at 25° C. of 1×10.sup.7 Pa or less. The cured resin layer can be formed from a resin composition that has a cure shrinkage of 5% or less.

Asphalt binders are modified using fractional products from waste tire pyrolysis, using an initial step of i) at least partially pyrolyzing, separately from such asphaltic binder, whole rubber articles or size-reduced rubber particles to provide one or more pyrolyzed rubber fractions including a pyrolyzed oil fraction having a selected minimum initial boiling point or flash point, and ii) removing some or all polycyclic aromatic hydrocarbon (PAH) compounds from such pyrolyzed oil fraction to provide a reduced-PAH and preferably translucent pyrolyzed oil fraction that may be combined with an asphaltic binder to provide a modified asphalt composition.

The present disclosure relates to a method and manufacturing method for a tire tread composition having absorption properties with high electric conductivity and excellent wear resistance. Specifically, the present disclosure relates to the fabrication of a tire composition to be used as a non-pneumatic tire, the tire composition can be used as a mobile electrode with a water supply means that can identify the location of defects in the buried conductor using the tire electrode manufacturing with improved conductivity and contact resistance with the ground even though the tire compound has wear resistance by lowering the water swelling rate compared to the previous technology.
