These master batches are manufactured
with different loadings of titanium dioxide, the principal pigment.
We offer grades upto 75% titanium dioxide loading for various applications.
Customers can choose from pure
white and whites with blue undertone. The grades of titanium dioxide
are carefully chosen to ensure high opacity and good dispersion.
The base carrier selected has total compatibility with the polymer
being coloured.
These master batches are manufactured
with PE, PP and PS base carriers, depending on the application.
The selection
of Titanium Dioxide is done carefully considering the type of final
application. Only rutile grades of Titanium Dioxide are used.
• The Selection of for a Specific applications is made carefully
considering various critical factors like, High Speed and High Temperature
Extrusion, where lacing problem is very common.
• Multilayer films manufactured through High Speed Extrusion or
processing of low MFI Polymers may result in build up of an undesired
material on the die lip forming rollers etc. can cause the disruption
in production and quality of the product.
• When the final article is exposed to direct Sunlight it tends
to change its colour due to induced UV degradation. That may also
be an effect of the white pigment used in colouring of the particular
product, where antiyellowing character is required which is purely
based on the coatings applied on the TDO.
Various masterbatches are developed for the different applications
are as follows :
a) General purpose or commodity films
b) Injection / Blow / Roto Moulding applications
c) Flexible packaging
d) High Speed and High Temperature Extrusion
e) Extrusion Coating / Lamination
f) Multilayer film extrusion, etc.
