YF 39 S

YF 39 S

YF 39 S is a medium-high fluidity homopolymer designed for the production of staple fibres. YF 39 S exhibits excellent anti-gasfading properties.
YF 39 S offers a high process stability and a good thermal-bonding ability.
YF 39 S is mainly used for the production of staple fibres for non-woven fabrics for feminine care products, diapers, medical disposables, wipes, filters and linings.
