Recycled feedstock only works in manufacturing when the quality is proven, not assumed. Vanden provides polymer analysis that verifies what a material is, how it will perform, and whether it meets your exact specification - before it enters your production line.
We combine trained polymer specialists, on-the-ground grading frameworks, and lab-backed testing across our three material labs to remove uncertainty from every shipment. Our teams assess recyclability, contamination, colour, and end-use suitability at source, then validate polymers through structured lab analysis. This gives you consistent feedstock, qualified for performance, with full traceability and compliant documentation.
We confirm polymer type using lab-grade identification methods, so your feedstock matches your process and end use.
We measure melt flow and key indicators that affect how material runs on your line - reducing variation and production risk.
Material is graded on the ground, then verified in the lab for contamination levels and recyclability, protecting output quality.
We assess colour requirements and standardise grades against defined benchmarks to support stable, repeatable manufacturing.
We produce batch-level technical reports internally to evidence material quality, support qualification, and maintain full traceability where required.
Polymer analysis at Vanden is built on specialist training and hard evidence. Our teams are regularly trained to the highest standard, and every decision is supported by lab data - not guesswork.
We assess materials at source using proprietary systems, for recyclability, contamination, colour and end-use suitability.
Every batch is tested against your specification - polymer type, melt flow, density behaviour, contamination limits and more.
We homologate and qualify materials so they perform consistently in production, shipment after shipment.
For manufacturers, polymer analysis isn’t a “nice to have.” It prevents the issues that stop lines, damage reputation, and waste time.
We believe in transparency and traceability – from detailed polymer analysis, and trial runs matched to your production process, right through to material source to cost-plus pricing models and index-linked contracts.
