Marun-V79S
1 product description
V 79 S is a high fluidity polypropylene homopolymer for the
production of staple fibres with improved thermo-bonding
ability for nonwoven fabrics.
The product exhibits excellent antigasfading properties.
V 79 S offers an outstanding process stability and
spinning behaviour on short-spinning lines and some
specific long-spinning lines.
The thermal-bonding ability is high and allows the production
of nonwoven fabrics with a higher tear strength or with a lower
weight per m2 for the same strength. The fabrics made with
V79 Sare characterised by softness, textile- like appearance
and tear resistance.
The typical applications are coverstock for diapers, feminine
care products and incontinence pads. Other applications
are wipes, filters and fabrics for the clothing and furniture
industry.
