Polypropylene (PP)
Polypropylene supplied to a declared melt flow index, with the grade family confirmed in writing before the proforma invoice is issued.
The three families
| Family | Character | Typical use |
|---|---|---|
| Homopolymer (PP-H) | High stiffness and clarity, lower impact at low temperature | Raffia, BOPP film, fibre, injection housewares |
| Random copolymer (PP-R) | Better clarity and impact, lower melting point | Hot-water pipe, transparent containers |
| Block / impact copolymer (PP-B) | High impact, including at low temperature | Automotive parts, crates, industrial containers |
Grade selection by process
| Process | Melt flow direction |
|---|---|
| Raffia / woven bag | Low MFI — melt strength for tape drawing |
| BOPP film | Low to medium MFI |
| Injection moulding — thin wall | High MFI — flow into long thin cavities |
| Fibre / non-woven | High MFI |
| Thermoforming sheet | Low MFI |
| Pipe (PP-R) | Low MFI |
