Influence of Crosslink Density on Electrical Performance and Rheological Properties of Crosslinked Polyethylene. [PDF]

open access: yesPolymers (Basel)
To investigate the influence of the crosslinked polyethylene (XLPE) structure on electrical performance, various analytical methods were employed to study polyethylene structures with different degrees of crosslinking. Dynamic rheological analysis was conducted to determine material shear viscosity, dynamic viscosity, storage modulus (G′), loss modulus

The sulfur reversion process in natural rubber in terms of crosslink density and crosslink density distribution

open access: yesPolymer Testing, 2020
Abstract Unfilled natural rubber compounds composed of conventional (CV), semi-efficient (SEV), efficient (EV) and sulfur donor (SD) vulcanization systems were heat aged to promote sulfur reversion. Rheometry, hardness, strain-strain characteristics including Mooney-Rivlin analysis, equilibrium solvent swell and Double Quantum (DQ) Nuclear Magnetic ...

Regenerative potential of mouse neonatal intervertebral disc depends on collagen crosslink density [PDF]

open access: yesiScience
Summary: Intervertebral disc (IVD) defects heal poorly and can cause back pain and disability. We identified that IVD herniation injury heals regeneratively in neonatal mice until postnatal day 14 (p14) and shifts to fibrotic healing by p28.

Nanosponge Tunability in Size and Crosslinking Density [PDF]

open access: yesJournal of Visualized Experiments, 2017
We describe a protocol for the synthesis of linear polyesters containing pendant epoxide functionality and their incorporation into a nanosponge with controlled dimensions. This approach begins with synthesis of a functionalized lactone which is key to the pendant functionalization of the resulting polymer.

A novel practical approach for monitoring the crosslink density of an ethylene propylene diene monomer compound: Complementary scanning acoustic microscopy and FIB-SEM-EDS analyses

open access: yesPolymers and Polymer Composites, 2022
Tuning of the crosslink density (CLD) in the rubber compounds is very crucial for optimizing the physical and mechanical properties of the ultimate rubber products. Conventionally, CLD can be measured via rheological methods such as moving die rheometer (

Devulcanization of Natural Rubber in Composites with Distinct Crosslink Densities by Twin-Screw Extruder [PDF]

open access: yesMaterials Research, 2017
In this study, the effects of the devulcanization process realized by an intermeshing co-rotating twin-screw extruder (ICTSE) on three vulcanized Natural Rubber (NR) composites with different crosslink densities (CD) have been investigated. The extrusion
