Abstract: A cable intended for use in a nuclear environment includes one or more conductors, a longitudinally applied corrugated shield surrounding the one or more conductors, and a cross-linked polyolefin jacket layer surrounding the longitudinally applied corrugated shield. The cable conducts about 5,000 volts to about 68,000 volts in use and is radiation resistant and heat resistant. The cable comprises a life span of about 40 years or more when measured in accordance with IEEE 323. Methods for making a cable and a nuclear reactor utilizing such a cable are also provided.

Abstract: Fire retardant compositions including a base polymer, a fire retardant filler, and a fire retardant synergist are disclosed. The fire retardant compositions are halogen-free and heavy metal-free and can be crosslinked to form a cable insulation layer or a cable jacket. The cables can pass the UL VW-1 flame test. Cables having coverings formed from such fire retardant compositions are also described herein.

Abstract: Cables including a fire-retardant composition are disclosed. The fire-retardant compositions include an oxygen-containing base polymer, a primary filler, and an antimony-containing secondary filler. The primary filler can be a metal hydroxide. The fire-retardant composition can be halogen-free and exhibit an elongation at break of about 150% or more. The cable passes the UL 1581 VW-1 flame.

Abstract: Compositions including a thermoplastic elastomer or thermoplastic vulcanizate derived from a styrenic block copolymer having a reactive or crosslinkable hard block including aromatic vinyl repeat units and also preferably a crosslinkable soft block, and a non-olefin thermoplastic polymer or copolymer and preferably a compatibilizer such as the reaction product of a non-olefin thermoplastic polymer and a functionalized polymer such as a maleic anhydride functionalized styrenic block copolymer that is compatible with the styrenic block copolymer having a reactive or crosslinkable hard block, and optionally a linking compound. The vulcanizates are prepared by crosslinking the styrenic block copolymer in the presence of the non-olefin thermoplastic polymer and a suitable crosslinking agent, and optionally the compatibilizer, preferably utilizing dynamic vulcanization.
