PP Fiber Grade

Polypropylene grades for staple fiber, filament and nonwovens, selected by melt flow and spinning behavior. Send an RFQ.

PP grades for fiber and nonwovens

Fiber grades are homopolymers with a narrow molecular weight distribution for stable spinning. The MFR is chosen for the fiber fineness and line speed.

The grades below are those the producer lists for fiber production.

Picking a fiber grade

Staple fiber and filament: MFR around 12–25 g/10 min.
Spunbond nonwovens: MFR around 25–40.
Fine and meltblown fiber: Very high MFR, often controlled-rheology grades.

Typical applications

Staple fiber
Continuous filament yarn
Spunbond nonwovens
Rope and twine

Processing notes

No drying needed. Spinning temperatures are typically 230–280 °C. Gel content and ash are worth checking on the COA, as both cause filament breaks.

General guidance only; follow the producer's TDS for each grade.
