1. Crosslinking of Ethylene Copolymers
Sammanfattning : The chemical reactions taking place when crosslinking poly(ethylene-co-vinyltrimethoxysilane) (EVS) have been studied. Films of EVS were stored in water at 90 °C or treated at processing temperatures in a tubular oven. The different chemical groups involved in the reactions were then followed by FTIR after different treatment times. LÄS MER
2. Structural Aspects of Peroxide Crosslinking of Polyethylene
Sammanfattning : Despite major developments in the ways of polymerising ethylene (the processes as well as the catalysts) the use of polyethylene is still restricted in several applications due to its low melting point. This shortcoming can in some areas be overcome by the introduction of crosslinks between the polymer chains. LÄS MER
3. ALTERNATIVE POLYETHYLENE CROSSLINKING CONCEPTS FOR POWER CABLE INSULATION
Sammanfattning : We currently witness an accelerating shift from fossil energy sources to renewables driven by the urgent need to reduce carbon emissions. Wind, solar and hydro power is most abundant in places far away from the end user, which necessitates the efficient transport of electricity over long distances. LÄS MER
4. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard
Sammanfattning : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. LÄS MER
5. The Effect of Crosslinking on Morphology and Water Treeing in LDPE
Sammanfattning : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is made by peroxide initiated crosslinking of low density polyethylene. In recent years, polyethylene with unsaturations, i.e. LÄS MER
