Circular Cross-Linked Polyethylene Enabled by In-Chain Ketones. [PDF]

ACS Macro Lett
Cross-linked polyethylenes (PEs) are widely employed, but the permanent links between the chains impede recycling. We show that via imine formation with diamines keto-functionalized polyethylenes from both free-radical (keto-low-density PE, keto-LDPE) and catalytic (keto-high-density PE, keto-HDPE) nonalternating ethylene-CO copolymerization can be ...

Effect of the cross-linking agent on the cross-linking degree and electrical properties of cross-linked polyethylene

Materials Research Express, 2023
To study the effect of a cross-linking agent on the cross-linking degree and electrical properties of cross-linked polyethylene, different mass fractions of cross-linked polyethylene and their electrical properties were investigated.

Volumetric Wear of Highly Cross-Linked Polyethylene Sockets in Total Hip Arthroplasty Differs Among Brands: A Retrieval Study [PDF]

Journal of Functional Biomaterials
Outcomes after total hip arthroplasty (THA) remain limited by wear and wear particle reaction. Although highly cross-linked polyethylene (HXLPE) mitigated this issue, there are major differences among the various brands available.

Space Charge Measurement and Modelling in Cross-Linked Polyethylene [PDF]

Energies, 2020
Cross-linked polyethylene, commercially known as XLPE, is widely used as an insulating material in high voltage cables. However, space charge accumulation under the DC field is one of the most challenging problems in the further development of XLPE ...

Early failure of a modern moderately cross-linked polyethylene acetabular liner [PDF]

Arthroplasty Today, 2020
Modern polyethylene components for total hip arthroplasty have shown excellent long-term wear properties. However, among 204 primary total hip arthroplasty procedures performed by one surgeon using the Exactech Connexion GXL Liner, we identified 5 cases ...

Highly cross-linked polyethylene still outperforms conventional polyethylene in THA: 10-year RSA results [PDF]

Acta Orthopaedica, 2021
Background and purpose — Cup wear in total hip arthroplasty (THA) can be affected by different manufacturing processes of the polyethylene (PE). We report the long-term wear pattern differences, as well as early creep behavior, between conventional PE ...
