Abstract
Official abstract text for this publication.
The present disclosure provides a crosslinked polymeric composition. The crosslinked polymeric composition contains (A) a silane functionalized ethylene-based polymer and (B) inorganic hollow microspheres having (i) a D 90 particle size from 10 μm to 100 μm, (ii) a crush strength from 17 MPa to 140 MPa, and (iii) a density from 0.10 g/cc to 0.40 g/cc. The crosslinked polymeric composition has a tensile strength from 11 MPa to 40 MPa and a tensile elongation from 12% to 100%.
First claim
Opening claim text (preview).
We claim: 1. A crosslinked polymeric composition comprising: (A) from 75 wt % to 99 wt % of a silane functionalized ethylene-based polymer; (B) from 1 wt % to 25 wt % inorganic hollow microspheres having (i) a D 90 particle size from 10 μm to 100 μm; (ii) a crush strength from 17 MPa to 140 MPa; (iii) a density from 0.10 g/cc to 0.40 g/cc; wherein the crosslinked polymeric composition comprises bonds between the silane-functionalized ethylene-based polymer and the inorganic hollow microspheres, and the crosslinked polymeric composition having a tensile strength from 11 MPa to 40 MPa; and a tensile elongation from 12% to 100%. 2. The crosslinked polymeric composition of claim 1 , wherein the inorganic hollow microspheres are glass hollow microspheres having (i) a D 90 particle size from 30 μm to 100 μm; (ii) a crush strength from 17 MPa to 50 MPa; and a density from 0.20 g/cc to 0.35 g/cc. 3. The crosslinked polymeric composition of claim 1 comprising (A) from 80 wt % to 95 wt % silane functionalized ethylene-based polymer; and (B) from 5 wt % to 20 wt % inorganic hollow microspheres. 4. The crosslinked polymeric composition of claim 1 , wherein the crosslinked polymeric composition has a density from 0.650 g/cc to 0.800 g/cc. 5. The crosslinked polymeric composition of claim 4 , wherein the crosslinked polymeric composition has a dielectric constant from 1.80 to 2.06. 6. A coated conductor comprising: a conductor; and a coating on the conductor, the coating comprising a crosslinked polymeric composition comprising (A) from 75 wt % to 99 wt % of a silane functionalized ethylene-based polymer; (B) from 1 wt % to 25 wt % inorganic hollow microspheres having (i) a D 90 particle size from 10 μm to 100 μm; (ii) a crush strength from 17 MPa to 140 MPa; (iii) a density from 0.10 g/cc to 0.40 g/cc; wherein the crosslinked polymeric composition comprises bonds between the silane-functionalized ethylene-based polymer and the inorganic hollow microspheres, and the crosslinked polymeric composition having a tensile strength from 11 MPa to 40 MPa; and a tensile elongation from 12% to 100%. 7. The coated conductor of claim 6 wherein the coating directly contacts the conductor. 8. The coated conductor of claim 6 , wherein the inorganic hollow microspheres are glass hollow microspheres having (i) a D 90 particle size from 30 μm to 100 μm; (ii) a crush strength from 17 MPa to 50 MPa; and (iii) a density from 0.20 g/cc to 0.35 g/cc. 9. The coated conductor of claim 6 , wherein the crosslinked polymeric composition comprises (A) from 80 wt % to 95 wt % silane functionalized ethylene-based polymer; and (B) from % 5 wt % to 20 wt % inorganic hollow microspheres. 10. The coated conductor of claim 6 , wherein the crosslinked polymeric composition has a density from 0.650 g/cc to 0.800 g/cc. 11. The coated conductor of claim 6 , wherein the crosslinked polymeric composition has a dielectric constant from 1.80 to 2.06.
