Polymer
industry forms one of the largest segments in chemicals.
Every specialty additive, be it ADC or any Lubricant, Processing Aid, play
a very important role in the field of polymers, whether be it processing or
it's use. The use of these additives is derived like a pinch of salt.
Nelion Exports has been instrumental in promoting several plastic specialty
additives, as enlisted below:
Master batches:
Master batches Find Various Applications In The Plastic Industry. Master
batches are used as colorants in the plastic field as well as fillers in a
few applications.
The range of master batches offered include all types of colours with
differing filler / non filler content, Metallic shades, UV Masterbatches,
black master batch with carbon black loading from 30 - 45 %.
Masterbatches in all different shades with differing properties can be
offered based on the end application, operating parameters, base raw
material being used.
Other than the regular coloured masterbatches, we also specialise in the
supply of ANTI FABRILATION MASTERBATCH used in PP & HDPE woven fabrics,
masterbatches, that impart cost effectiveness as an additive for HM/HDPE &
LDPE / LLDPE films & masterbatches that surrogate polymer cost as well
as the cost of white master batch in Injection & Blow moulding
applications.
We have recently ventured into the supply for masterbatches used in
furniture moulding. These when added to polymer improves stiffness &
rigidity of article, improves moulding properties, improves thermal
stability, & aesthetic appearance of the product.
We can offer superior quality masterbatches against your requirement on
receipt of it's sample, the article produced using the sampled masterbatch &
some knowledge on the process parameters.
AZO Dicarbonamide (ADC):
AZO Dicarbonamide, Familiarly Known As ADC, Is An Efficient General Purpose
Chemical Blowing Agent For A Wide Variety Of Polymers In The Production Of
Expanded Articles.
Different grades of ADC are available in a range of particle sizes with a
very close distribution in self dispersible, activated and self dispersible
and coarser grades.
ADC grades, as is evident from the earlier elaboration, can be used with
almost all kind of polymers with all kind of processing techniques:
- Plastisol (Spread Coating / Calendaring), extrusion, injection
moulding, compression moulding, and rotational moulding. Processing
parameters and recommended formulations are different with different
polymers and are available on request.
- ADC Grades can be used for the production of foamed articles based on
Plasticized or Unplastized PVC, HDPE/LDPE, eva co-polymers, natural &
synthetic rubber, polypropylene & ABS. These are especially suitable
for PVC plastisol application where in it produces whiter foams with
uniform & fine cell structure.
- The ADC core grades are the blowing agent for rubber compounds where
these can be easily incorporated at the end of mixing process and
results in even dispersion.
- ADC core grades vulcanisates with extremely fine uniform cell
structure free from any discolouration or odor, can be obtained. Wall
papers, artificial leather cloth, floor and wall coverings, thermo
insulating materials, insulating sealant, carpet backing, cellular
ceramic, door sealing strips, profiles, sheets, foot wear midsoles
/insoles and automotive components are some of the application areas.
Lubricants:
Nelion Exports in association with it's associates offers a range of
speciality additives, that go for varied applications in Polymers, Paints,
Rubbers.
2 main additives used in the polymer industry are Lubricants &
Processing Aid, while for PVC, it is lubricant as well as stabilisers.
Lubricants reduce the friction, heat, wear & tear between 2 surfaces.
The surfaces could be between polymer molecules & of the equipment, or
between polymer molecules themselves. The action of lubricants is to
facilitate the smooth production runs without interruption & to attain a
technically & aesthetically sound final article.
Internal lubricant reduce the intermolecular friction before & during
melt formation of the polymer, they also reduce frictional heat built up
under shear, promote gelation, reduce melt viscosity & improve flow
properties to promote easier & faster flow through the equipment.
External lubricant reduces the friction & sticking between hot melt PVC
& working surfaces of machinery due to the presence of a layer &
interface. This eases the movement of stocks through the machinery &
prevents adhesion of the hot melt that would otherwise quickly result in
local formation of stagnant layers.
The lubricants offered find a wide range of application in PVC products,
namely garden hose, shoes /soles, pipes, cables, calendered sheets,
profiles.
Special lubricants are offered for plasticised PVC compounds to reduce
the melt viscosity for higher output & to produce a finished product
with superior aesthetic appearance.
Processing Aids:
Processing Aids Are Multifunctional Additives, Specially Designed For
Application Where Fillers / Pigments Need To Be Dispersed Uniformly In The
Polymer Matrix.
Addition Of Higher Filler / Pigments Can Lead To Various Processing
Problems & Defects In Finished Products, Such As :
- Non - Uniform Dispersion Of Fillers In The Polymer Matrix
- Excessive & Non Uniform Mould Skrinkage
- Poor Mechanical Properties Due To Inadequate Dispersion Of Filler
With Base Polymer
- Sticking Of The Filled Compounds To The Machinery During Processing
While conventional use of products like Waxes, Stearic Acid, etc
provide lubricating properties only, they do not help in the uniform
distribution/ bonding of fillers & pigments in the polymer matrix.
The processing aids helps overcome the above stated problems in processing
filled plastic compounds.
Procesing aids find application in Mineral Filled Masterbatches, Furniture
compounds, Wood Filled Compounds, PVC compounds, Antifabrialtion compounds,
Coloured Masterbatches, Filled Re-Inforced Thermoplastics & many many
more.
Stabilisers:
PVC is a versatile and resource efficient thermoplastic with an extensive
range of applications in virtually all areas of human activity.
Unlike most other thermoplastics, the majority of PVC applications have a
lifetime of between 10 and 100 years. This requires proven durability and
heat stabilisers play an important part in achieving such performance.
We offer the complete range for PVC stabilisers to be used in different
applications for PVC processing. These include:
- Lead Based Stabiliser
- Tribasic Lead Sulphate
- Dibasic Lead Stearate
- Dibasic Lead Pthalate
- Dibasic Lead Phosphite
- One Pack Stabiliser (P0 3 Top Flakes) Which Is The Largest
Selling Stabiliser For Rigid PVC Pipes At Competitive Rates In India
& Abroad
- Liquid Stabiliser
- Barium Cadmium
- Barium Cadmium Zinc
- Barium lead
- Barium Zinc ( Kicker)
- Barium Zinc ( Stabiliser & Kicker)
- Cadmium Zinc
- Barium Calcium Zinc
- Complex Metal Stabilisers
In addition to the above Polymer Additives, we also offer a range
of additives, such as flow promoters, slip additives, anti block additives,
anti static agents, synthetic waxes, pigment wetting agents, viscosity
depressants, speciality plasticizers, secondary antioxidants, antifog
additives, filler / pigment coating additives, non phthalate plasticisers to
suite any application in polymer.
Chemicals
The
paint & ink additives offered include:
The
rubber processing additives offered by NELION EXPORTS play a vital role in
various rubber applications. Likewise as polymers, the various chemicals
required for rubber processing include flow promoters, lubricants, release
agents, dispersing agents, antistatic agents, antitack agents, slip agents,
& processing aids, antioxidants, extenders, re-inforcing material,
accelerators & pigments. 
Galvanising
process produces a durable abrasion resistant coating of metallic zinc and
zinc-iron alloy layers bonded metallurgically to the steel base and
completely covering the work piece, thereby providing corrosion resistance &
increasing the life of the product.
