Recycled polyamides

Recycled (secondary) polyamides are regenerated PA compounds made from process or post-industrial scrap (runner systems, defective parts, trimmings). Material Wizard supplies certified secondary polyamides with particle-size control, stabilization and additional compatibilization, retaining 70–90 % of the mechanical properties of virgin polyamide. What a recycled polyamide is A recycled polyamide is not "landfill waste" but a technologically reprocessed product. The feedstock consists of flash, runners and defective mouldings from production areas. After grinding, cleaning, pelletizing and stabilization, we obtain a material suitable for moulding, extrusion and compounding. Economic benefit Price 30–50 % below virgin PA. Stable supply — Material Wizard controls the feedstock flow from several producers. Guaranteed batch-to-batch repeatability of properties. Suitable for series production of industrial parts. What we offer Secondary unfilled PA6 — for general-purpose technical parts, housings and fasteners. Secondary unfilled PA66 — higher heat resistance, a standard for non-critical automotive parts. Reclaimed glass-filled PA (PA66 GF30, PA6 GF30) — an economical alternative to virgin GF compound for metal-replacement parts. Coloured secondary grades — predominantly black, with stable colours available on request. Applications of secondary PA Technical parts for industrial use — brackets, housings, fittings. Automotive parts without OEM certification requirements — clips, holders, trims. Furniture hardware — hinges, brackets, rollers. Agricultural products — housings, containers. Construction hardware — plugs, stops. Components for repeated industrial use. Limitations of secondary PA Not for food contact — no FDA/EU 10/2011 certificates for most grades. Not for medical use — not certified to ISO 10993. Predominantly black colour — stable light colours are difficult to achieve. Slight property scatter of ±10 % between batches (controlled by certificate). Possible reduction in impact resistance of 20–30 % compared with virgin material. Quality control Material Wizard provides a quality certificate for each batch of secondary PA: moisture content, MFI, tensile strength, Charpy impact strength, melting temperature. Testing is carried out on our own equipment in accordance with ISO 1133, ISO 527 and ISO 179. How to choose a secondary PA for your product Material Wizard will select a secondary polyamide for your specific conditions: level of mechanical loads, temperature range, required dimensional accuracy, appearance of the part. For series production, we offer stable property-scatter ranges with a contract for regular supply. Request a free consultation.
