Polyethylene Curing / Crosslinking

AkzoNobel’s range of organic peroxides for the curing of thermoplastics is the world’s largest, including a number of crosslinking peroxides for the production of (crosslinked) polyethylene pipes, tubes and power distribution cables.

PEX-a pipes and tubes 

To further improve the product properties of high density polyethylene (HDPE), the polymer matrix can be crosslinked. Using organic peroxides a three-dimensional network is formed in a one-step-cure-process (PEX-a).

We have also helped to create a new concept for the production of peroxide-crosslinked polyethylene pipes used in gas and domestic water distribution systems.

Power distribution cables 

Our products also find their way in the low density polyethylene (LDPE)-based cable industry.

AkzoNobel's organic peroxides are used for crosslinking LDPE while our Ketjenblack EC superconductive carbon blacks are also used in semi-conductive applications such as the medium and high voltage cables.
