Polynar Co P YI250 PP Homo Datasheet

″Polynar P-YI-250″ is a high melt flow homo-polymer polypropylene for the production of CF, BCF and fine denier staple fibers at medium to high spinning speeds and exhibits excellent antigasfading properties. ″Polynar P-YI-250″ offers a high homogeneity,stable extrusion and excellent processability on both short and long spinning lines.This grade allows a high stretch ratio and gives tough and resilient fibers. ″Polynar P-YI-250″ is suitable for nonwoven fabrics for diapers, medical-sanitary applications, surgical garments, geotextiles and wipes. Another typical application is high tenacity continuous filament for straps for backpacks, sport bags, bulk bags and handles for big and safety belts. Continuous filament with medium tenacity is used for upholstery and sportswear and heavy duty clothing. ″Polynar P-YI-250″ is also suited for the production of bulked continuous filament for thermo bonding and carpets. ″Polynar P-YI-250″ is suitable for food contact.
