Effect of silane and peroxide concentration on grafting behaviour of high-density polyethylene
thesis
posted on 2018-10-09, 14:09 authored by Gulshan S. AhmedSilane-crosslinked polyethylene was introduced for wire and cable insulations, and is
now used extensively for the manufacture of domestic hot and cold water pipe
systems. Silane crosslinking of polyethylene is a two stage processes, the first stage is
the grafting of organosilane molecules onto polyethylene, and the second stage
involves crosslinking through the alkoxysilane (Si-OCH3) groups to form siloxane
(Si-O-Si) linkages. It is the grafting stage that influences the materials behaviour and
therefore properties and performance of the crosslinked product.
ISOPLAS crosslinkable polyethylene manufactured at Micropol Ltd has shown slight
variations in measurable properties amongst materials processed in the extruders,
which are determined using quality control tests in order to give a rough guide to the
processability. Therefore, a detailed study was carried out to gain a better
understanding of processing and structure-property relationships of the material. [Continues.]
