Polymer Products enforces a strict 9-stage closed-loop identification architecture. Every single elastomeric bridge bearing is individually marked and permanently traceable to its virgin raw polymer lot, internal steel reinforcement batch, vulcanization press cure parameters, and certified NABL/IRC:83 test reports.
Raw elastomer & steel shims
Individually serialized units
Permanent side identification
Full proof load test correlation
A clear identification system helps ensure that each bearing can be traced and verified through its relevant product and manufacturing details.
The identification format is illustrated in the chart below.
Rigorous inward inspection of raw natural rubber/chloroprene polymer, steel laminate plates, bonding adhesives, and curing agents against Mill Test Certificates (MTC).
Every weighed masterbatch of rubber compound and chemically treated steel shim lot is assigned a unique, traceable internal Batch ID code.
Routing job cards accompany the materials across two-roll mills, calender sheeting, steel shot-blasting, and Chemlok primer coating stations.
Elastomer layers and steel plates are precisely assembled in high-precision machined moulds and vulcanized under monitored hydraulic press pressure & temperature.
LOT NO., BEARING SIZE & UNIQUE IDENTIFICATION NO.
Permanent indelible hot-embossed marking vulcanized directly onto the outer protective elastomer side layer.
Comprehensive verification of dimensional tolerances, elastomer hardness (IRHD), compressive stiffness, shear modulus (G), and 1.5× design proof load testing.
High-durability waterproof polythene shrink-wrapping with heavy-duty weather-proof inspection tags, client project markers, and pallet ID barcodes affixed.
Stored in dedicated covered, temperature-controlled racking bays segregated by client project code, inspection release status, and curing maturity dates.
Dispatch on wooden pallets with correlated Manufacturer Test Certificate (MTC), Inspection Release Note, Gate Pass, and Site Installation Instructions.
Each elastomeric bearing manufactured by Polymer Products carries an indelible identification marking on its outer side surface. This enables bridge engineers, site quality auditors, and highway authorities to instantly verify design ratings, compound lot, and manufacturing provenance decades after installation.
