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 Antioxidants 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
Antioxidants. 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 Peroxides and Antioxidants.
Online dosing offers a significantly longer shelf-
life. Using alternative peroxides can even result in
increased extruder outputs and longer production
runs.
Key Feature of Ultra-Mix© :
•
•
•
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.

Can be simply installed on any extruders within
one day.
System is independent of the extrusion line PLC,
therefore no requirement to connect unit to the
extruders line control system.
System can work up to 7 solid compounds + 2
liquids (Silane) or (Peroxide and Antioxidant).
Very high mixing precision of solid + liquid.
Software can store more than 500 recipes
System is certified ATEX-95
Automatic Silane Safety storage cabinet and
pumping system.
Very high saving on extrusion compounds.
