MFR control in recycled PP
The flow behaviour of rPP feedstock rarely arrives ready for the target process. There are two opposite directions: reducing or increasing MFR. Choosing the right direction is the first technical decision.
These two products are not alternatives to each other; they have opposite functions. Choosing the wrong direction costs both material and line time.
Which product for which application?
| Flow too high; melt strength insufficient | NexCircle® R403 (reduces MFR) |
|---|---|
| Flow too low; mould filling limited | NEXAMITE® R202 (increases MFR) |
| rPP stream contaminated with rPE | NexCircle® R403 |
| Long flow path / thin-wall part | NEXAMITE® R202 |
Products
