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 &#x3bc;m in size.

Process for foaming polyolefin compositions using a fluororesin as a nucleating agent

A process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination of (A) azodicarbonamide, 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 the mixture is not solely composed of alkali metal citrate.

The present disclosure provides a process. In an embodiment, the process includes blending a broad molecular weight distribution (MWD) ethylene-based polymer having an 121/12 ratio from 55 to 85 with a narrow MWD ethylene-based polymer having an 121/12 ratio from 20 to 50. The process includes forming a blend component comprising from 20 wt % to 45 wt % of the broad MWD ethylene-based polymer, from 80 wt % to 55 wt % of the narrow MWD ethylene-based polymer, and optional carbon black. The blend component has a density from 0.925 g/cc to 0.955 g/cc and an 121/12 ratio from 30 to 55. The process includes extruding the blend component over a conductor at a rate greater than 1.02 m/s, and forming a conductor jacket having a surface smoothness from 30 &#x3bc;-inch to 80 &#x3bc;-inch.

The process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination an azodicarbonamide (ADCA) and a fluororesin at a ADCA: fluororesin weight ratio of 60:40 to 20:80. The synergic effect between these two nucleating agents results in a higher nuclei density and a foamed product with a smaller cell size as compared to processes using and products produced by the use of neat PTFE or neat ADCA alone as the nucleating agent.
