Semi-conductive/non-conductive
water blocking tape
Semi-conductivewater blocking tapes are used for water blocking
between power cable components. Its swelling characteristic is
believed to be superior to traditional water blocking tape due to
the lack of a covering fabric. It offers a replacement for traditional
semi-conductive tapewith no causticity.
Non-conductive water blocking tapes are used for water
blocking between the components of optical fibre cable,
communication cable and power cable. Shenyang Jinggong Cable Material Co Ltd
manufactures semi- and non-conductive water blocking tape and yarns and offers an
efficient service, worldwide.

SAMP and DS&M
started a new
partnership
SAMP, manufacturer of extrusion cable
lines, and DS&M, well-known in the
field of dosage and control systems
production, have together developed
a new technology which enhances the
performance of the whole extrusion
process and is believed to be much
cheaper than traditional production
lines. After extensive experimentation,
research and development, SAMP and
DS&M have created a new extrusion
module suitable for the vast majority of
granulated material.
The group is called “Multiflex 25 Extrusion
Module” and is made of a 25-diameter
extruder integrated with a dosage and
mixing unit of polymers and silane,
conveniently developed to improve the
homogenisation among solid and liquid
components before plasticising.
Excellent results obtained for over a year
on a pilot production line created the
basis for a technical and commercial
partnership between SAMP and DS&M,
who recently signed a specific agreement.
SAMP and DS&M presented their new
project during the wire 2008 exhibition in
Düsseldorf.

New flame retardant
compound for use in
high-heat environments
Dow Wire & Cable has introduced Unigard™ RE HFDA-1492, a reduced-emissions
flame retardant compound for use in wires and cables needed in high-heat
environments, such as those found in automotive engines and appliances.
Capable of tolerating temperatures of up to 125°C, the new compound also offers
important processing, environmental tolerance and ease of installation benefits
while meeting industry and end-use market specifications.
Unigard RE HFDA-1492 is a colourable, peroxide-crosslinkable, polyethylene
copolymer insulation compound. It is approximately 4% lighter than traditional
materials used in automotive wire and cable applications and delivers more
output per pound, offering system cost benefits as a result. Designed to enable
the manufacture of cables that are more flexible with lighter weight and improved
colour retention, HDFA-1492 also has a low specific gravity of 1.35 to help reduce
the consumption of compound per cable length. Tests with HFDA-1492 have
also shown a 20-50% improvement in line speeds on Dow customers’ existing
equipment, compared to a commercial automotive compound. A broad
processing window, from 105°C to 135°C, also supports potentially higher line
rates.
Unigard RE HDFA-1492 additionally addresses important environmental and North
American legislative requirements by providing PVC-like performance with LS0H
(low smoke zero-halogen) advantages at a competitive cost.
