Alumina, Alumina Trihydrate (ATH), Sodium Alumina, Calcined Alumina, High Alumina Cements & Refractory Castables, BRIEF DESCRIPTION OF PRODUCTS :-
ALUMINA TRIHYDRATE ( ATH )
Of the Common fillers used in Plastics, Rubber, FRP, SMC, DMC moulding and other polymers only Alumina Trihydrate has
flame retarding and smoke suppressing properties as well as being an economical resin extender. Alumina Chemical &
Castables is the leading developer & Processor of ATH.
ATH is used in polyester resins. However with increased attention being given to smoke & toxic fume emissions, ATH has
found large volume application in vinyl as a low smoke, non toxic replacement for antimony and in polyurethane, latex,
neoprene foam system, Rubber, wire & Cable insulation, vinyl walls & flooring coverings and epoxies. Alumina Trihydrate
acts as a flame retardant and smoke suppressor because of its thermodynamic properties. Its endothermic dehydration
cools the plastic & Rubber parts and dilute with water vapour those combustible gases that do escape. The latter is
probably the main phenomenon associated with smoke suppression other excellent performance include electrical and

track resistance.
Alumina Trihydrate widely use in Paper Industries as a whitening agent in place of titanium dioxide.
ATH is also use in Paints Industries. ATH can replace upto 25% of the Titanium dioxide pigment & therefore is an
economical extender reducing production cost.
IDENTIFICATION OF GRADES :-
Alumina Trihydrate CHW grade & CHD grade :-
These are unground coarse particle having approx. 150 micron size. Former CHW grade contain moisture from 3 - 8% and
later grade CHD is dry moisture free, free flowing material. These grades are use in ferric non ferric alum manufacturing
and glass manufacturing.
Alumina Trihydrate ATH - 325 Grade :-
This is ground grade passes 325 mesh. Average particle size is 10 - 15 microns.
This grade use specially in Paper Industries as a whiting agent in place of titanium dioxide. In thermoplastics, thermosets
SMC / DMC moulding, FRP, PVC, use as a filler material, flame retardant and / or smoke suppressor.
In rubber industries ATH disperses well prior to vulcanization and curing. Functions include improving surface texture and
abrasion resistance electrical arcing and tracking resistance,
improved stiffness, flame retardant and / or smoke suppressor.
Alumina Trihydrate ATH - 800 grade:-
This is finely ground grades consisting entirely of superfine pass through 800 mesh. Average particle size 1.5 - 5 microns.
This grade use specially in XLPE,PVC Cable & wire coatings, polymer industries, & Paints Industries
Alumina Trihydrate surface treated material available on request.

CALCINED ALUMINA
Calcined Alumina is a commercial Alumina or Aluminum Oxide. It is white powder. One of the outstanding characteristics
of Calcined Alumina is its hardness which is 9 on mohs scale. There is board industrial field of applications for this type
of alumina and number of distinctive grade are produced to meet various needs.

SODIUM ALUMINATES
We are manufacturing Sodium Aluminates having consistent quality with our experience work men under observation of
strict Q.C. personal. Our spare capacity of manufacturing this product is 300 MT per month.
It appears in white powder form containing granules 0.1 to 4 mm in size.
Available in two grades
Sodium Aluminate - Wet (as is basis)
Sodium Aluminate -dry
Application : In the manufacturing process of Alumina hydrate
: It is use in soap industries
: It is used as a water treatment chemical for removing phosphates & fluorides
from municipal & industrial waters.
: In paper industry Sodium Aluminates increases the opacity retention of fibers
& filling material & paper strength. Also it stabilize the PH value of the water
circulations & increases the dispersion stability of filler. It is also use in
Sulphite recovery operation in paper making.
: It is use As a pigment in paint. Adding Sodium Aluminate to titanium dioxide

CALCIUM ALUMINATE CEMENT : HAC - 8R
General Information :-
HAC-8R is an alumina rich calcium aluminate cement ( CAC ) with 80% Al203 and very low impurities content. This cement
has been indigenously manufactured as an equivalent to imported calcium refractory cements, namely SECAR - 80 and
CA-25 grades.
HAC-8R cement imparts the following properties to high performance castable refractories :
Excellent mechanical performance in all temperature range High refractoriness and lot properties Improved volume stability.
Very low silica and iron oxide contents in HAC - 8R cement makes it particularly suitable for certain refractory applications
under hydrogen or carbon monoxide atmosphere.
As a result of controlled processing and the calcium aluminate mineralogy, HAC-8R cement is designed to have most
consistent setting, rheology and strength characteristics. Due to
these unique rheology and consistency, HPC - 8R can be used to manufacture refractory castables or monolithics in LCC,
ULCC and conventional systems combining with wide range or refractory aggregates and other special raw materials.
