Quality systems and in-house lab.
ISO 9001:2015 certified. We test every batch for melt flow, ash, moisture and dispersion before despatch.

-
01
Incoming raw material
Every incoming material, calcium oxide, calcium carbonate, titanium dioxide, pigments, carriers and additives, is checked against the supplier's certificate for purity, moisture and particle size. Off-spec lots are held back.
-
02
In-process sampling
Samples are pulled at every stage, blending, coating, extrusion and pelletising. Melt flow, density, dispersion and active content checked against the master grade card.
-
03
Finished-goods sign-off
Finished batch tested against the full grade spec, melt flow, ash, moisture, particle size, colour and visual pellet check. QC signs off before sealing.
-
04
Despatch and traceability
Every pouch carries a batch ID linking back to the lot, line, operator and test record. A Certificate of Analysis ships with the consignment; retain samples kept for the shelf-life.
Consistency is the simplest form of trust. We've delivered it, batch after batch, since 1997. Shreegopal Polychem
Polymer lab, adjacent to the production floor
The lab is right next to the production floor, so a sample drawn at the extruder is back with the operator before the next batch starts.
- 4 dedicated test instruments on the bench
- Lab-scale twin-screw extruder for pilot batches
- Specialised tests (FTIR, DSC, TGA, GPC) routed to accredited external labs
- Same application chemist handles brief to production
-
Melt Flow Indexer (MFI)
How the carrier resin flows at standard temperature and load. Confirms a grade behaves the same lot after lot.
-
Moisture analyser
Karl Fischer titration and loss-on-drying. Used on desiccant grades, sensitive carriers and finished pellets.
-
Particle size analyser
Sieve and laser diffraction. Verifies particle size on fillers (calcium carbonate, calcium oxide) and fine silicas.
-
Filter-pressure dispersion test
Compound pushed through a fine mesh filter, the pressure rise shows how well the additive is dispersed. The industry-standard dispersion check.
Datasheets, CoAs and SDSs available on request
A Certificate of Analysis ships with every consignment. Wider QMS documents and our ISO certificate are available under NDA for serious enquiries.

Frequently asked questions
What quality tests are performed before despatch?
Three checks before despatch. First, on raw material: moisture, particle size, ash and a visual on carriers, pigments and additives. Second, in the compounding line: melt flow, dispersion (filter pressure value), colour against the reference, homogeneity. Third, on the finished pellet: shape, bulk density, moisture and final melt flow against the grade sheet. A CoA with the lot number, test values and tolerances ships with every consignment.
Is your lab independently audited?
Yes. We are ISO 9001:2015 certified and audited annually by an accredited body. The current certificate is available on request. Customer audits of the Jodhpur facility are welcome with reasonable notice.
Can you run a custom formulation trial?
Yes. We regularly build custom masterbatches and additive blends matched to a specific resin, line speed and end-use. The flow: brief, lab pilot on a twin-screw or single-screw extruder, dispersion check, 1-2 kg trial sample with a draft CoA, your line trial, sign-off against the agreed spec, then production. Same application chemist from brief to production.
What is the typical R&D timeline for a new grade?
A tweak to an existing grade (different loading, different carrier, shade match): 5-10 working days from brief to trial sample. A new formulation or difficult dispersion problem: 3-4 weeks. Pantone or RAL shade matches usually return within a week. Firm timeline confirmed once we have seen the brief.
What lab equipment do you use?
In-house: melt flow (MFI), moisture (Karl Fischer, loss-on-drying), dispersion (filter pressure value), particle size, ash content (muffle furnace), colour delta (spectrophotometer) and a lab-scale twin-screw extruder for pilot batches. Specialised tests (FTIR, DSC, TGA, GPC) run through accredited external labs when needed.
How do you ensure batch-to-batch consistency?
Three controls. Raw material locked to approved suppliers with incoming QC against a fixed spec. Process settings (temperature, screw speed, throughput) per grade fixed in an SOP. Finished pellets tested against the same reference values every lot, within agreed tolerances. The CoA on every consignment shows the actual numbers, so you can spot any drift lot to lot.
Can you provide a Certificate of Analysis (CoA) with every batch?
Yes. Every consignment ships with a CoA showing the grade, lot number, manufacture date, test results (melt flow, moisture, dispersion, colour delta, ash, where relevant) and agreed tolerances. References the master grade sheet you signed off at trial, so you can compare consignments lot by lot.
