Wire & Cable ASIA – November/December 2007 41
ExxonMobil Chemical Company has introduced Vistalon™ EPM* rubber 722
which can cost effectively improve processability and cable flexibility in medium
and low-voltage wire and cable applications.
In comparison with conventional EPDM, the metallocene-based product can
provide processing improvements while exhibiting similar performance.
Compared with cross-linked polyethylene (PE), it offers improved performance
and excellent flexibility at low temperatures. And, it has improved electrical
properties compared with metallocene EPDMs.
“We have developed Vistalon EPM 722 for customers looking for improved
productivity during cable manufacture and increased flexibility and durability in
final cable construction,” said Ulf Nilsson, global EPDM product manager.
The new product is supplied in pellet form, making it clean and easy to use.

Cost-effective Vistalon
Process Control Corporation, a supplier
of auxiliary equipment for the plastics
processing industry, has expanded its
product line to include the Gravimetric
Inventory Management System.
With an increased number of
processors searching for a method to
weigh and store either re-pelletised
material or delivered raw pellet
materials, PCC recognised the need for
an inventory management system.
The system will accurately weigh
re-pelletised materials prior to being
re-processed or stored as inventory.
The system can also be used to verify
delivered resins before entering them
into inventory.
The system can be configured to
operate in a continuous mode for
loading silos or other surge bins for
storage or as a batching system for
loading Gaylord boxes for storage.
The system can provide totals for a
given production shift, a complete
production run or an overall running
total of material. It runs automatically
with little or no operator intervention
logging shift weight totals.
Pellet material is conveyed either from
a pelletiser, storage or delivery unit
into a surge hopper via a pressure or
vacuum system.
The surge hopper has a high level view
window for quick visual inspection of
the material level within the bin, as well
as a clean-out door and a high-level
proximity sensor. The high level proxi-
mity sensor is provided to shut down the
conveying system and prevent the
system from over-filling. The material is
then discharged from the surge hopper
through a slide-gate into a weighed
hopper. Finally, the material is discharged
through a second metering gate into
either a Gaylord box or is conveyed to
either a storage silo or storage bin via a
vacuum or pressure system.
The entire system is controlled with an
easy-to-use touch-screen interface.
The inventory data can be printed or
transferred to an existing supervisory
type inventory control system.

New system gives PCC control
New annealer from GER
GER SA, a supplier of second-hand
wire and cable machinery, has launched
a new continuous resistance annealer
for copper wire.
This annealer model, with an AC 22 kW
motor, has a wire diameter range
from 1.0-3.5mm. The rating is 3,000
Amp and the annealing voltage is
approximately 45V. The annealing
transformer and control system are
built in two separate cabinets. A steam
generator with sufficient capacity is
included.
