The company behind the compound.
Every pellet leaves the line with a number, a datasheet, and a name behind it.
Polyazin began in 1999 as a small compounding workshop with one extruder and one conviction: that a polymer producer should stand behind every lot with real, measured data. Today the company runs dedicated masterbatch and polyethylene compounding lines, an in-house QC laboratory, and a planned production calendar that keeps stocked grades moving to customers on schedule.
The catalogue is deliberately focused — optical brightener and anti-slip masterbatches, geomembrane and general-purpose PE compounds — so each grade gets the engineering attention it deserves. Every batch ships with its TDS and CoA, from Esfarayen to customers on six continents.

Compounding & extrusion lines
Dedicated masterbatch and PE compounding lines with tightly controlled melt histories and lot-to-lot consistency.
In-house QC laboratory
Every lot is tested to ISO 1133-1, ISO 3451 and ISO 787 before release — the numbers on the datasheet are measured, not quoted.
R&D & custom matching
Additive packages tuned to your process — carrier, loading and stabilization matched to the part and its service life.
Six steps from resin to release.
Resin intake
Base polymers and additives lot-checked on arrival.
Formulation
Each recipe weighed to the gram, batch by batch.
Compounding
Twin-screw melt blending under controlled shear.
Pelletizing
Cut, cooled and dried to a uniform pellet.
QC release
ISO 1133-1 · 3451 · 787 on every single lot.
Pack & export
Bagged, palletized and documented for the route.

We don’t sell polymers — we sell the certainty that a part performs on its ten-thousandth cycle.
