Z 21 S

Z 21 S

Z 21 S is a high melt flow homopolymer with a narrow molecular weight distribution for the high speed production of low denier continuous filament for spun bonded, nonwoven fabrics.
The major applications for spun bonded fabrics made of Z 21 S are diapers, medical and sanitary tissues, protective fabrics for agricultural, industrial and medical applications, backings and linings for the furniture, bedding and carpet industries.
Z 21 S can also be used for the production of partially oriented yam and bulked continuous filament.
