E-XHEAD extrusion SA Presents
New Patented Product: Ultra-Mix©
One Step Process Compounding Unit
Traditional XLPE cables are produced with ready-made compounds from various suppliers.
These compounds have predefined recipes of base LDPE, Silane or Antioxidant and
Peroxide. Ultra-Mix© has been developed, for combining separate compounds online
during extrusion.
Online compounding offers improvements
in several aspects. There is a wide range of
suppliers offering base LDPE grades for cable
insulation without Silane or Peroxide and
Antioxidant. Customers have a large freedom of
choice. Traditional XLPE compounds are limited
to using chemicals that are solid at room
temperatures, otherwise the compound would
suffer from chemical sweat out. Shelf life makes
storing premix compounds a concern.
The use of online dosing removes some of these
restrictions and gives the cable manufacturer a wider
selection of Silane or Peroxide and Antioxidant.
Online dosing offers a significantly longer shelf-
life. Using alternative peroxides can even result in
increased extruder outputs and longer production
runs.
Our is a system for both Silane or Peroxide and
Antioxidant dosing. The system consists of one to
seven feeders with gravimetric measurement for
accurate dosing. When different solid compounds
are ready as a batch, Precision injection of Silane or
Peroxide and Antioxidant is effectuated. While Liquid
and Solid are mixed together next batch is under
preparation.
