WebApr 14, 2024 · Cross-linked polyethylene (XLPE) with excellent mechanical, heat resistance and insulation performance has been extensively used as an insulating material for high-voltage (HV) cables [ 1, 2, 3 ]. XLPE is generally obtained after dynamic extrusion and crosslinking reaction of low-density polyethylene doped with additives (PEDA) [ 3, 4 ]. WebLow cross-link densities increase the viscosities of polymer melts. Intermediate cross-link densities transform gummy polymers into materials that have elastomeric properties and …
How can I calculate the cross linking density of a polymer?
WebJul 17, 2001 · Cross-linkers are the metals, such as aluminum citrate and chromium. Polymer concentrations range from 100 to 1200 mg/L, normally 400 to 800 mg/L. The … WebCrosslinked polymer microspheres with surface functional groups such as carbonyl, ... As the crosslink density increases, failure becomes more adhesive (no residue left on the test panel) maximizing the holding power of the adhesive. As one continues to add crosslinker, the polymer slowly loses its viscoelastic character, the holding power ... database_result_cached
