Analysis of Space Charge Formation in LDPE in the Presence of Crosslinking Byproducts [PDF]

open access: yes, 2012
Cross-linking byproducts are suspected to be the main contributing factor in space charge formation observed in XLPE. To investigate the mechanism behind this phenomenon, low density polyethylene was soaked into three main crosslinking byproducts ...

The trapping characteristic of low density polyethylene in the presence of crosslinking by-products

open access: yes, 2009
The by-products of dicumyl peroxide (DCP) from the crosslinking process such as acetophenone, cumyl alcohol and α-methylstyrene are said to be the sources of space charge formation in XLPE cable due to deep traps in the chemicals. However, by using space-
