H 39 S

H 39 S

H 39 S is a very high fluidity homopolymer for the high speed production of very low denier BCF and CF. H 39 S exhibits excellent antigasfading properties.
Because of its high homogeneity and very high MFR,
H 39 S offers stable extrusion and excellent processability on both short and long spinning lines. This grade allows a high stretch ratio and gives tough, resilient and colourfast fibres.
H 39 S is eminently used for the high speed production of bulked continuous filament for carpet face yarns.
Another major application is the production of high tenacity continuous filament for straps for backpacks, handles for big bags and safety belts.
Continuous filament with medium tenacity is used for upholstery and heavy duty clothing.

H 39 S is suitable for food contact.

1) Measured at230°C under a load of 2.160 kg, with a standard nozzle having a diameter of 2.095 mm.
2)
Average nominal value referred to a tensile injection mo’;ded specimen, type I (ASTM D 638).
3)
Typical mechanical property values measured on standard specimens, injection moulded under conditions designed to minimise orientation and in-moulded stresses and in line with the conditions generaIy used by industrial converters. Specimens are concitioned at room temperature (ASTM D618 - Procedure A).
4)
The compositon of the product complies with the regulations in force in major European countries concerning polypropylene resins for use in food contact applications. Further details can be supplied on request.
