Property levels are set relative to unfilled virgin injection-moulding PA6: tensile strength 68 MPa and tensile modulus 2640 MPa, roughly 20 % below virgin. Elongation at break and impact strength drop further — this is inherent to recycled feedstock, where reprocessing shortens the polymer chain and energy absorption suffers before stiffness does. The stated 12 % and 3.2 kJ/m² therefore reflect a realistic level rather than a conservative one.

What does not change: density, melting point 222 °C, HDT/B 187 °C, moisture uptake and processing windows. These are properties of the polymer and its matrix, and recycled feedstock does not shift them. In practice the thermal capability of the part matches virgin PA6; the limitation lies in mechanical loading.

A note on melt viscosity: recycled feedstock typically shows lower viscosity than virgin material, meaning a higher MVR. This affects machine setup — injection speed and packing should be re-optimised rather than carried over from a virgin grade. MVR is confirmed per batch.

On the comparison baseline. The values above are referenced to an unfilled nucleated injection-moulding PA6. Nucleation increases crystallinity, so such a PA6 shows a higher modulus and lower elongation than standard non-nucleated grades. For PA66 the baseline is a standard unfilled injection grade. This is why the modulus of Examid® PA6R G exceeds that of Examid® PA66R G — a property of the comparison baseline, not an advantage of PA6 over PA66 as a polymer.

Formulation is matched to the application. The figures are typical for the class; the exact specification and batch variation range are agreed per application and fixed in the technical specification.

Examid® PA6 GF30 BK-R is a black polyamide 6 with 30% glass fiber based on 100% recycled polyamide feedstock. A position for projects where cost and recycled content (for ESG reporting) matter and mechanical requirements are moderate.

Honest numbers: tensile strength of 130 MPa and flexural modulus of 7000 MPa — 20–25% below virgin PA6 GF30. Meanwhile flow is high (MFR 45 g/10 min), and shrinkage and heat resistance (HDT 215 °C at 0.45 MPa) match virgin grades. For housings, medium-load brackets and internal parts this margin is sufficient.

Economics is the main argument: substantially lower price than virgin compound with consistent batch quality. Validate suitability for specific parts through batch testing.
