PE Conductive Black |
Applications:- |
1. |
Extruded Products:
Conductive Films and Bags:- These provide protection to highly
sensitive ESDS devices which are susceptible to static voltages. The
bags are intended for storing electrostatic sensitive devices such
as ICs to avoid damages by electrostatic discharge. The ESD sensitive
parts and assemblies can be stored in these bags during intermediate
stages of testing, transport, packing and field repairs.
Heavy duty bags can be used for the handling of explosive powders
and electronic components and also as drum liners.
PE CB compound can be used for production of flexible hose, sheet
slock, apron, gloves in clean room assembly conditions in electronic
industry.
The PE CB compound is also suggested for use if required with PP carrier
resin to produce twist tape in raffia bag/FIBC construction. The black
conductive/antistatic tape discharges the static build-up in transporatation,
handling and storage of electrostatic prone sensitive products. |

Injection Moulded Products:-
Containers for electronic parts, twist traps, heel protectors
for use in static charge generation environment.

Processing:- |
|
a. |
Moisture:- PE CB
compound may absorb when stored under damp/humid conditions. It may,
therefore, be necessary to dry the compound prior to use. Usually
2-4 hours in a hopper drier to sufficient to reduce the mositure content
to an acceptable level. |
|
b. |
Extrusion:- The compound can
be processed on conventional Polyethylen extrusion equipment. The
following parameters may be set for extruding tubular film.
Barrel |
Die |
110-180ºC |
190ºC |
Actual extrusion temperature would depend on the nature of equipment
used. As aid to the elimination of moisture porasity, it is advisable
to cool the extrudate as soon as possible after it leaves it dies. |
|
c. |
Injection Moulding:-The compound
can be processed on most types of injection moulding machinery but
because of high filler content, the use of preplasticising machinery
is recommended. As a general guide, a melt temperature of between
190ºC and 230ºC should prove adequate Mouldings would have
a reasonable finished when moulded at 220ºC. |
|
d. |
Packing:- The compound is pellet
form in packed in 25 kg HDPE raffia bag with internal PE liner. It
should be stored in a dry place. |
