What that means in practice

The same 955 kg/m³ and MFR 1.5 as MB6561 — what separates them is a slip agent giving a controlled opening torque, which no headline specification will show. Offered one against the other, the additive package is the question and not the numbers.

If these numbers are not something you work with daily, our HDPE grades and pricing guide explains what they measure and how prime, off-spec, regrind and regranulate differ.

What to check before buying BorPure MB6562

• Closure resin is bought on stress-crack resistance and organoleptics as much as on the numbers. A cap that taints bottled water has failed however well it moulded.
• Ask whether the grade contains a slip agent. Borouge's pairs — MB6561 against MB6562, MB5568 against MB5569 — have identical density and melt flow and differ only there.
• Get the food contact and drinking water compliance documentation for the specific lot, not the generic grade declaration.
• For lightweighted closures, stress-crack resistance matters more than stiffness. Ask what the material was originally specified into before assuming it swaps.
