Consistency is the single most valuable attribute of an industrial polymer supplier. A processor who receives material that performs identically batch after batch can run a tighter, more efficient operation. At DOT RAD, our ISO 9001-certified quality control process is engineered to deliver exactly that consistency.
Batch Sampling
Every production lot is sampled according to a statistically derived plan. Samples are taken at multiple points along the compounding line to capture any in-batch variation. Each sample set is sealed, logged, and traced to its production run through a unique lot number.
Core Test Methods
- Melt-flow rate (MFR) — verifies the rheological grade matches specification
- Density — confirms polymer composition and crystallinity
- Tensile strength & elongation — mechanical performance verification
- Impact resistance (Izod/Charpy) — toughness under sudden load
- Moisture content — ensures stable processing for the converter
- Ash / filler content — validates formulation accuracy
A grade is only released for shipment once every specified parameter falls within tolerance. Out-of-spec material is quarantined and never reaches a customer.
Documentation & Traceability
Each shipment is accompanied by a Certificate of Analysis (CoA) listing the measured values for that specific lot. Full traceability — from raw-material intake through compounding to dispatch — is maintained for every batch, enabling rapid root-cause analysis should any field issue arise.
This rigorous approach is why industrial buyers across 50+ export markets trust DOT RAD polymers for their most demanding applications.
