 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.
