Bright ReflectiveWire Finish
The GPS/PDH system in cleaning version is a novelty that brings a new dimension to
wire cleaning process, benefiting from the unique PDH multi-function technology,
enabling an automatic control of crucial process parameters (pressure/temperature/
viscosity, compound injection speed and thermal stability). In cleaning operation, most
of these parameters communicate together in an extremely sensitive and automatic
multi-way interaction, providing drawn wire in bright glossy finish for plating quality,
at high-speed, cleaned and polished to reflective appearance, in-line, with liquid
compounds or semi-solid high-viscosity products containing anti-corrosion additives.
The GPS/PDH system is installed in the last draft of a
drawing machine to clean drawn wire from lubricant
contaminants. It simultaneously performs surface
cleaning and polishing effect, providing a high level
of cleanliness of dry drawn wire, without the need for
aggressive chemicals, and it operates at all practical
speeds at virtually zero energy consumption. The main
reason behind this achievement has been the cost,
wire quality and environment factors.
The GPS/PDH wire cleaning system operates with
a wide range of liquid and semi-solid lubricating
solutions in continuous IN and OUT motion, evacuating lubricant contaminants out
of the compressed chamber in an open or closed circuit, completely eliminating wire
tunnelling effect and pressure fluctuation, enabling the highest cleaning speed, up
to 12m/s (2,400ft/min). A light draft performs wire cleaning and polishing (reflective
finish) in a single pass, clean wire leaving the unit completely dry.
The system is particularly recommended for cleaning applications of wires drawn in
severe conditions, resulting in increased heat and burned lubricant tightly bound on
the wire surface. The system is compact, and easy to install and to use.

Solutions for fibre optics
At wire China 2010, PolyOne focused on its portfolio of solutions for optical fibres. The product family includes several grades of
ECCOH™ and ECCOH™ PF low smoke and fume, zero-halogen (LSFOH) compounds, as well as OnColor™ and OnCap™ colourant and
additive solutions.
PolyOne Corp sees rising global demand for optical fibre is being led by China, Japan and Korea. In China, government stimulus
funds promoting rural infrastructure and major construction programmes have significantly expanded the optical fibre market. In the
past, optical fibre cables were mainly for outdoor use and, as such, did not require flame retardant sheathing materials. Increasingly,
however, bandwidth providers are bringing fibre optics into buildings. These cables must not only be flame retardant, but must also
contain materials that are low-smoke, low-fume, and non-halogenated (also called LSFOH, for Low Smoke and Fume, Zero Halogen).
Responding to this trend, PolyOne developed a range of solutions for the FTTB and FTTH markets, called ECCOH™ and ECCOH™ PF
compounds. Both product families are said to meet the requirements for LSFOH material use inside buildings, and are classified as a
PolyOne Sustainable Solution.
In addition to excellent flame retardance, these solutions offer low smoke and low toxicity benefits, and include the following
features:
ECCOH™ compounds meet tight buffering and sheathing requirements, offer low corrosion, very low shrinkage (less than 1%), •
good mechanical strength to prevent fibre breakage, and low memory retention to ensure good attenuation properties
ECCOH™ PF grades are recommended for mini-ducts through which fibre is routed. These compounds offer good flame •
retardance, while an inherent stiffness allows easy installation and provides bend radius control
OnCap™ anti-static compound enables optical fibres to be blown further. This compound can be coextruded as an internal •
layer 0.5mm thick. A patent is pending on the application using LSFOH as an outer layer and antistatic slip compound as the
internal layer
Each ECCOH™ compound can also be provided with suitable OnColor™ colour concentrates to match specific requirements, with
masterbatches available for other materials such as HDPE, PBT and TPU. PolyOne also offers OnCap™ UV additive and slip additive
masterbatches suitable for FTTx applications.
