KeyForm P1311 is a polypropylene homopolymer for continuous-filament extrusion. It has a very narrow molecular-weight distribution and an anti-gas-fading stabilisation package.
Description
KeyForm P1311 is a polypropylene homopolymer for continuous-filament extrusion. It has a very narrow molecular-weight distribution and an anti-gas-fading stabilisation package. Typical applications include high-tenacity yarns and spunbond nonwovens. The TDS gives a typical melt flow rate of 25 g/10 min (230 °C/2.16 kg).
