Abstract: La presente invención se relaciona con componentes de cable óptico fabricados de una mezcla polimérica extrudida de polipropileno cristalino modificado con uno o más polímeros de modificación de impacto. Los polímeros de modificación de impacto se seleccionan de un interpolímero de multi-bloque de olefina, un compuesto de bloque de olefina y combinaciones de los mismos. Opcionalmente, la mezcla polimérica además puede comprender un elastómero diferente del polímero de modificación de impacto. La mezcla polimérica también puede contener uno o más aditivos. Los componentes del cable de fibra óptica pueden seleccionarse de tubos protectores, tubos centrales y tubos centrales ranurados.

Abstract: Thermally conductive materials comprising an olefin block composite and a thermally conductive filler, where the thermally conductive filler is present in an amount sufficient to increase the thermal conductivity of the olefin block composite relative to the olefin block composite in its neat state. Such thermally conductive materials can be used in various articles of manufacture, such as a thermal interface material or a molded heat dissipation component.

Abstract: Optical cable components fabricated from an extrudable polymeric blend of crystalline polypropylene modified with one or more impact-modifying polymers. The impact-modifying polymers are crosslinked and can be selected from a polyolefin elastomer, an olefin multi-block interpolymer, an olefin block composite, and combinations thereof. Optionally, the polymeric blend can further comprise a compatibilizer. The polymeric blend may also contain one or more additives. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes.

Abstract: A wireless-communications-tower component being at least partially formed from a foamed metal. The foamed metal has a density of less than 2.7 g/cm3, a thermal conductivity greater than 1 W/m·K, and a coefficient of thermal expansion of less than 30 µm/m·K. Such a foamed metal can be an open-cell foamed metal or a closed-cell foamed metal. Foamed metal components can also present a non-foamed or polymer-coated surface.
