Abstract
A semiconductive composite material consisting essentially of a non-polar organic polymer and an electrical conducting effective amount of an ultra-low-wettability carbon black. Also a method of making the composite material; a crosslinked polyethylene product made by curing the composite material; manufactured articles comprising a shaped form of the inventive composite material or product; and methods of using the inventive composite material, product, or articles.

A semiconductive composite material consisting essentially of (A) a non-polar polyolefin polymer and an electrical conducting effective amount of (B) an ultra-low-wettability carbon black (ULW-CB), which has a Brunauer-Emmett-Teller (BET) nitrogen surface area of from 35 to 190 square meters per gram (m2/g), measured by BET Nitrogen Surface Area Test Method (described later);
- and an oil absorption number (OAN) from 115 to 180 milliliters of oil per 100 grams (mL/100 g), measured by Oil Absorption Number Test Method;
- and a water uptake of from 400 to 2400 parts per million (ppm, weight), measured by Moisture Uptake Test Method.
A semiconductive composite material consisting essentially of (A) a non-polar polyolefin polymer and an electrical conducting effective amount of (B) an ultra-low-wettability carbon black (ULW-CB), which has a surface wettability profile characterized by wettability ≤0.0101 at surface coverage of 0.02, and wettability ≤0.0101 at surface coverage of 0.04, and wettability ≤0.0099 at surface coverage of 0.06, and wettability ≤0.0111 at surface coverage of 0.08, and wettability ≤0.0113 at surface coverage of 0.10, measured by inverse gas chromatography (IGC) according to Wettability Test Method;
- and a water uptake of from 400 to 2400 parts per million (ppm, weight), measured by Moisture Uptake Test Method.
