Examid\u00ae PA6R G is an unfilled injection-moulding polyamide 6 based on recycled feedstock. It targets parts that need the full thermal performance of PA6 with a moderate mechanical margin: housings, brackets, internal structural elements and fastening parts.<\/p>\n
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 \u2014 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\/m\u00b2 therefore reflect a realistic level rather than a conservative one.<\/p>\n
What does not change: density, melting point 222 \u00b0C, HDT\/B 187 \u00b0C, 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.<\/p>\n
A note on melt viscosity: recycled feedstock typically shows lower viscosity than virgin material, meaning a higher MVR. This affects machine setup \u2014 injection speed and packing should be re-optimised rather than carried over from a virgin grade. MVR is confirmed per batch.<\/p>\n
On the comparison baseline.<\/strong> 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\u00ae PA6R G exceeds that of Examid\u00ae PA66R G \u2014 a property of the comparison baseline, not an advantage of PA6 over PA66 as a polymer.<\/p>\n 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.<\/p>","protected":false},"excerpt":{"rendered":" Examid\u00ae PA6R G is an unfilled injection-moulding polyamide 6 based on recycled feedstock.
