Abstract: A polyolefin composition is foamed by a process in which a nucleator is used, and the nucleator comprises 80% or more of unagglomerated fluororesin particles and/or agglomerates of fluororesin particles in which both the unagglomerated particles and the agglomerates are less than 1 μm in size.

Abstract: The process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination of (A) a fluororesin, and (B) a mixture of (1) a first component consisting of at least one of citric acid and an alkali metal citrate, and (2) a second component consisting of at least one of an alkali metal citrate, a di-alkali metal hydrogen citrate, an alkali metal dihydrogen citrate and an alkali metal bicarbonate with the proviso that if the first component of the mixture is an alkali metal citrate, then the second component of the mixture is not an alkali metal citrate.

Abstract: A filling composition comprises (A) a mineral oil having a kinematic viscosity from 80 cSt to 100 cSt at 40° C.; (B) a styrene-ethylene/propylene diblock copolymer; and (C1) a propylene/ethylene copolymer having a weight average molecular weight (Mw) from 5,000 to 200,000 or (C2) an ethylene/propylene copolymer having a weight average molecular weight (Mw) from 5,000 to 200,000. The filling composition is used as a filling composition in a buffer tube.
