PEX-a Pipes & Tubes
AkzoNobel offers a number of key organic peroxides for the production of crosslinked polyethylene (PEX-a) pipes and tubes. These are used in gas and domestic water distribution systems, as well as in district heating and other industrial applications.
New PEX-a technologies
Over the last few years, the PEX-a industry has faced several new technologies. New production requirements such as longer production runs and higher line speed in combination with novel pipe design have triggered new developments. This has brought equipment producers and raw material suppliers together to work on one-step multi-layer pipe production, improved IR-heating technology, 'single-stage production processes' and other concepts.
Consequently, polymer producers introduced new products and technologies which demand safer and more robust organic peroxides.
Organic peroxides for PEX-a
Our organic peroxides expertise was used to help develop and fine-tune high-performance cross-linking peroxides to enable single-stage production of PEX-a pipes.
Beside the standard crosslinking peroxides such as Trigonox B, AkzoNobel also provides a more suitable and safer 'drop-in' peroxide: Trigonox 145-E85.
In addition, Trigonox 311, a peroxide with an extremely high thermal stability, allowing significantly more freedom during the extrusion process of HDPE-compounds has been introduced for the production of PEX-a pipes and tubes. On average, 20-30°C higher melting temperatures can be applied with the use of Trigonox 311 compared to the standard peroxides used in this application.
