摘要： 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 selected from an olefin multi-block interpolymer, an olefin block composite, and combinations thereof. Optionally, the polymeric blend can further comprise an elastomer other than the impact-modifying polymer. 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.

摘要： The process of foaming a polyolefin composition using as a nucleator a combination of a fluororesin and a boron nitride at a fluororesin-to-boron nitride weight ratio of less than 4:1. The synergistic effect between these two nucleating agents results in a higher nuclei density and a foamed product with a smaller average cell size as compared to processes using and products produced by the use of neat PTFE or neat boron nitride alone as the nucleating agent.

摘要： 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.
