Pluskim's Diverse Methods in Quality Control

In polyurethane systems, consistent performance is not solely the result of formulation—it also depends on rigorous quality control before, during, and after production. At Pluskim, quality is not a final checkpoint but an integrated, process-wide standard. By applying multiple QC techniques, Pluskim ensures that every batch meets technical, functional, and safety specifications.

Raw Material Incoming Inspection

All raw materials are tested for:

Hydroxyl value
Acid number
Viscosity
Color (Gardner scale)

This ensures formulation consistency and input reliability from the start.

Production Control Based on Formulation

During production, each recipe is controlled with:

Refractometry for density measurement
Rheology and viscosity checks (Brookfield)
Reactivity profile analysis (cream time, rise time, gel time)
Precise digital ratio weighing and validation

No batch is released unless it fully complies with the intended formulation.

Final Product Testing (Lab-Based)

Pluskim's in-house lab tests include:

FTIR spectroscopy for chemical structure validation
Shore A/D hardness tests (ISO & DIN standards)
Tensile & elongation measurements
Density and cell structure under cross-section microscopy
Fire resistance, thermal conductivity, rebound resilience
Closed-cell content and water absorption (for rigid foams)

Continuous Process Monitoring

SAP/ERP-based batch tracking ensures full traceability
Sample archiving for every production lot
Customer feedback is logged and reviewed in QC cycles
Benchmarking and R&D comparisons for product development

At Pluskim, quality is built into the system. Through its diversified and robust QC methods, every product delivered is a result of controlled production, technical excellence, and customer-focused reliability.
