What that means in practice

MFR 75 is very high flow indeed, and it exists for one reason: thin wall packaging, where the melt has to travel a long way through a thin section before it freezes off. It is not a general-purpose grade and should not be priced as one.

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

What to check before buying BorPure HJ333MO

• Melt flow rate decides whether it fills the part, and PP is measured at 230°C with a 2.16kg load. A PP figure quoted at 190°C is either a PE number or an error — Borouge's own PP web page carries exactly that mistake; their datasheets do not.
• Ask whether it is nucleated. Nucleation shows up as shorter cycles and better clarity rather than as a line on the specification, and it is a real difference in what the material is worth.
• Homopolymer, random copolymer and block copolymer are not interchangeable at the same MFR. Confirm which one is actually being offered.
• For anything off-spec or regrind, ask how many heat histories it has had. PP chain-scissions on reprocessing and the melt flow climbs, so the MFR you are quoted may not be the MFR that arrives.
