    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: Crosslinkable, semiconductive, peroxide-free thermoplastic compositions having a stable volume resistivity of less than 1000 ohm-cm comprise, based on the weight of the composition: A. 60-90 wt% silane-functionalized polyethylene; B. 0.5-20 wt% organopolysiloxane containing two or more functional end groups; C. 10-20 wt% high conductivity carbon black, e.g., a carbon black having an average particle size of 50 nm or less, a surface area (BET) of 700-1250 m2/g, and an oil absorption (DBP) of 300-500 ml/100 g; and D. 0.05 - 0.2 wt% crosslinking catalyst.

    Abstract: A composition comprises a) at least one ethylene-based copolymer comprising units derived from ethylene and from greater than 0 wt% to less than or equal to 3.5 wt%, based on the total weight of the ethylene-based copolymer, of units derived from at least one polar comonomer; b) at least one antioxidant; c) an organic peroxide; d) optionally, at least one co-agent; and e) optionally, at least one water tree retardant or electrical tree retardant. The composition comprises from 0 wt% to less than 1 wt%, based on the total weight of the composition, of olefin-based polymers other than the ethylene-based copolymer. The composition has a dissipation factor of from 0% to less than or equal to 0.1% at a temperature of 120°C and an electrical stress of 6 kV/mm. The composition is suitable for use as an insulation layer in cables.
